Its purpose is to manage the preferences of the handler, as well as provide interface functions to commonly used features as saving or loading the review buffer or the command history. It contains also functions to identify an I/O stream as ViNCEd stream or to find the intuition window related to such a stream. It provides also functions to give back this pointer to allow iconification or closing of that window. Various vectors in this library serve more as "patchable hook" then "callable functions", i.e. they can be patched to replace various ViNCEd features as the TAB expansion or the keyboard parser. It contains furthermore miscellaneous functions used by the SetVNC preferences editor which are open to other applications as well. Last but not least, it contains job control functions which allow user applications to put their programs to foreground or background. vnc.library/VNCInputHandler vnc.library/VNCInputHandler NAME VNCInputHandler - collect input events, send them to windows SYNOPSIS ievent = VNCInputHandler ( ievent , vncbase ); d0 a0 a1 struct InputEvent * VNCInputHandler ( struct InputEvent *, struct VNCLibrary *); FUNCTION Collects a linked list of input events, and sends the information to the open ViNCEd windows. INPUTS ievent - a linked list of InputEvents. vncbase - a pointer to the vnc.library, must be passed in a1 for this function. RETURNS the input event passed in. NOTES This function is called as a part of the ViNCEd input handler. Input events should be usually made available thru the input device and not by calling this function. BUGS SEE ALSO input.device, VNCImInputHandler() vnc.library/VNCImInputHandler vnc.library/VNCImInputHandler NAME VNCImInputHandler - collect input events, send them to windows SYNOPSIS ievent = VNCImInputHandler ( ievent , vncbase ); d0 a0 a1 struct InputEvent * VNCImInputHandler ( struct InputEvent *, struct VNCLibrary *); FUNCTION Collects a linked list of input events, and sends the information to the open ViNCEd windows. INPUTS ievent - a linked list of InputEvents. vncbase - a pointer to the vnc.library, must be passed in a1 for this function. RETURNS the input event passed in. NOTES This function is called as a part of the ViNCEd input handler. The only difference between this function and VNCInputHandler() is that this is the "immediate input handler" which hooks into the input handler chain in front of the intuition input handler, whereas VNCInputHandler() hooks in behind intuition. The reason for providing two input handler functions is to have the timer events available which are usually swallowed by the intuition input handler, but needed by ViNCEd. Input events should be usually made available thru the input device and not by calling this function. BUGS SEE ALSO input.device, VNCInputHandler() vnc.library/VNCRawKeyConvert vnc.library/VNCRawKeyConvert NAME VNCRawKeyConvert - convert raw keycodes to CSI/ESC/ASCII sequences SYNOPSIS converted = VNCRawKeyConvert ( kmrequest ) d0 a0 LONG VNCRawKeyConvert ( struct KeymapRequest * ) FUNCTION Convert an input event, pointed to by the KeymapRequest structure into a sequence of CSI codes or ASCII codes, pass back the number of characters in the buffer, or -1 if the buffer overrun. This function will make use of the ViNCEd extended CSI sequences if the flags in the KeymapRequest structure say so. INPUTS kmrequest - a pointer to the following structure: struct KeymapRequest { struct InputEvent *kmr_Event; struct Keymap *kmr_Keymap; struct ExtMap *kmr_ExtMap; ULONG kmr_Flags; char *kmr_Buffer; ULONG kmr_Length; ULONG kmr_Qualifier; ULONG kmr_ExtFlags; }; kmr_Event: the input event to process. This is only allowed to be a single input event, not a chain of input events. It MUST be of type IECLASS_RAWKEY. kmr_Keymap: a pointer to a standard console.device keymap to use for conversion of non-ViNCEd specific keys. kmr_ExtMap: a pointer to the ViNCEd extension of a keymap, found in the preferences, for example. kmr_Flags: a set of flags, defined as follows: KMF_EXTENDED: Reply extended ViNCEd CSI sequences as well. KMF_NUMLOCK: NumLock is active. You've to keep trace of this flag yourself. kmr_Buffer: the output buffer to place the characters in. kmr_Length: the size of this buffer. kmr_Qualifier: initialize to zero. kmr_ExtFlags: initialize to zero. RETURNS the number of characters put into the output buffer, or -1 if the buffer overrun. Furthermore, the following fields of the structure are set for you: kmr_Qualifier: the keyboard qualifier set in the input event. kmr_ExtFlags: the following flags can be made use of: (meaning: there are more you should not depend on) VPKF_NOSCROLL this key shall not snap back the window contents VPKF_NOTABXQ this key shall not terminate a TAB expansion VPKF_ASCII this key was found by an ASCII match and not a raw key code match VPKF_XTENDED this is a ViNCED extended function VPKF_IMMEDIATE this function must evaluate immedate, even if the type ahead buffer is active. NOTES BUGS SEE ALSO devices/keymap, vnc/prefs.h, the ViNCEd guide vnc.library/SwitchTABExpansion vnc.library/SwitchTABExpansion NAME SwitchTABExpansion - toggle the TAB expansion on/off SYNOPSIS success = SwitchTABExpansion ( cn, onoff ) d0 a5 d0 LONG SwitchTABExpansion ( struct ViNCWindow *, LONG ) success = SwitchTABExpansion_CN ( onoff ) d0 d0 LONG SwitchTABExpansion_CN ( LONG ) FUNCTION Toggle the TAB expansion on or off. INPUTS cn - a pointer to the ViNCWindow structure describing the ViNCEd window. This structure MUST HAVE BE LOCKED with LockCNWindow() before if you call this. See NOTES below. onoff - A boolean flag indicating whether expansion should be allowed or not. RESULTS a boolean success/failure indicator. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative TAB expansion to hook in here. It is, however, called by the library itself in case the TAB expansion must be disabled or enabled. BUGS SEE ALSO LockWindow(), vnc/window.h vnc.library/HandleTabExpansion vnc.library/HandleTabExpansion NAME HandleTabExpansion - launch a TAB expansion SYNOPSIS success = HandleTabExpansion ( cn, len, pos, dir, buf, owner) d0 a5 d0 d1 d4 a0 a1 LONG HandleTabExpansion ( struct ViNCWindow *, ULONG, ULONG, ULONG, ULONG, char *, struct ViOwner *) success = HandleTabExpansion_CN ( len, pos, dir, buf, owner) LONG HandleTabExpansion_CN ( ULONG, ULONG, ULONG, char *, struct ViOwner *) FUNCTION Run a TAB expansion asynchronously in background on the provided information. Reinsert the expansion into the VINCEd window specified by "cn". INPUTS cn - a pointer to the ViNCEd main structure to handle. MUST be LOCKED with LockWindow(). len - the length of the line with user data to be expanded. pos - the position of the cursor within this buffer. Zero is the leftmost position. It is allowed in the range of 0..len. dir - direction/type information of which TAB function to use. 0,1: first Tab function, forwards resp. backwards 2,3: second Tab function, ... 10,11: sixth Tab function. More might be defined in the future. buf - buffer with the data to be expanded. This is the FULL line of user inputs only. All printed characters have already been filtered out. "pos" is the cursor position relative to the FILTERED data. owner - pointer to the ViNCEd owner structure where the current directory to look at should be extracted from. ViNCEd *tries* to make sure that this owner is stable and does not go away as long as the expansion is running. RESULTS a boolean success indicator whether the tab expansion could be launched successfully. It DOES NOT indicate whether the expansion worked or not. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative TAB expansion to hook in here. It is, however, called by the library itself to launch the TAB expansion. Note again that this call is asynchronous. SEE ALSO LockWindow(), vnc/owner.h, vnc/window.h vnc.library/AbortTabExpansion vnc.library/AbortTabExpansion NAME AbortTabExpansion - try to cancel a running expansion SYNOPSIS success = AbortTabExpansion ( cn ) d0 a5 LONG AbortTabExpansion ( struct ViNCWindow * ) success = AbortTabExpansion_CN ( ) d0 LONG AbortTabExpansion_CN ( VOID ) FUNCTION Tries to cancel an already running Tab expansion. However, this routine may fail to do so in case the user opened a TAB expansion requester which cannot aborted due to system limitations. It will return -1 even in this case. INPUTS cn - a pointer to the ViNCEd window in which the TAB expansion is taking place. MUST BE LOCKED before calling this routine with LockWindow(). RESULTS -1 if the abort signal was send successfully. This DOES NOT mean that the expansion was aborted successfully, however. 0 on failure. 1 if the tab expansion was disabled. No signal is send in this case. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative TAB expansion to hook in here. It is, however, called by the library itself in case the TAB expansion must be aborted. BUGS SEE ALSO LockWindow(), vnc/window.h vnc.library/LockWindow vnc.library/LockWindow NAME LockWindow - arbitrate exclusive access to a ViNCEd window SYNOPSIS LockWindow ( cn ) a5 VOID LockWindow ( struct ViNCWindow * ) LockWindow_CN ( ) VOID LockWindow_CN ( VOID ) FUNCTION Arbitrate exclusive access rights to the given ViNCEd main structure. By calling this function, the handler part of ViNCEd, as well as any other task is not allowed to modify any part of this structure. INPUTS cn - a pointer to the ViNCWindow structure, the main structure of ViNCEd. RESULTS NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window for most functions that require a pointer to this structure. Don't hold this lock permanently. DO NOT send any Dos I/O requests while you're holding this lock since this results in a deadlock. The handler part of ViNCEd will not be able to operate as long as you're holding this lock. Call UnlockWindow() to release the control. This call DOES nest! Assembler programmers might note that this call does not modify any registers, but it requires the a5 (and a6) register to be setup correctly. BUGS SEE ALSO UnlockWindow(), vnc/window.h vnc.library/UnlockWindow vnc.library/UnlockWindow NAME UnlockWindow - release access from a ViNCEd window SYNOPSIS UnlockWindow ( cn ) a5 VOID UnlockWindow ( struct ViNCWindow * ) UnlockWindow_CN ( ) VOID UnlockWindow_CN ( VOID ) FUNCTION Release access from the given ViNCEd main structure. INPUTS cn - a pointer to the ViNCWindow structure, the main structure of ViNCEd. RESULTS NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window for most functions that require a pointer to this structure. This call NESTS. Every call to UnlockWindow() must match one and exactly one call to LockWindow(). Assembler programmers might note that this call does not modify any registers, but it requires the a5 (and a6) register to be setup correctly. BUGS SEE ALSO LockWindow(), vnc/window.h vnc.library/FindCNWindow vnc.library/FindCNWindow NAME FindCNWindow - locate a ViNCEd window related to a file handle. SYNOPSIS cn = FindCNWindow ( file ) d0 d1 struct ViNCWindow * FindCNWindow ( BPTR ) FUNCTION This library function finds the ViNCEd main structure related to a file handle, as returned by the Open() function of the dos.library and required by other dos functions. Related to this operation, a closed intuition window will pop-open by this called and is not allowed to be iconified or closed until UnFindCNWindow() is called. INPUTS a BPTR to a file handle, describing the stream to the ViNCEd handler. RESULTS Either the pointer to the ViNCEd main window, or NULL if the stream is not a ViNCEd file. This call will also open the intuition window of the ViNCEd stream. NOTES You MUST call UnFindCNWindow() as soon as you don't need the intuition window any more. The ViNCEd main structure will not go away as long as you keep the stream open, but the intuition window may. EVERY CALL TO FindCNWindow() returning non-NULL must be matched by one and exactly one call to UnFindCNWindow(). You MUST NOT call UnFindCNWindow() if FindCNWindow() returned NULL. SEE ALSO UnFindCNWindow(), Open(), vnc/window.h, the ViNCEd guide vnc.library/UnFindCNWindow vnc.library/UnFindCNWindow NAME UnFindCNWindow - reallow iconification of a ViNCEd stream. SYNOPSIS UnFindCNWindow ( file ) d1 VOID UnFindCNWindow ( BPTR ) FUNCTION This library function undoes the side effect of FindCNWindow() and allows iconification and closing of the intuition window attachted to a ViNCEd stream. MUST BE CALLED if FindCNWindow() returned non-NULL. INPUTS a BPTR to a file handle, describing the stream to the ViNCEd handler. RESULTS NOTES You MUST call UnFindCNWindow() as soon as you don't need the intuition window any more. The ViNCEd main structure will not go away as long as you keep the stream open, but the intuition window may. EVERY CALL TO FindCNWindow() returning non-NULL must be matched by one and exactly one call to UnFindCNWindow(). You MUST NOT call UnFindCNWindow() if FindCNWindow() returned NULL. SEE ALSO FindCNWindow(), vnc/window.h, the ViNCEd guide vnc.library/GetVNCPrefs vnc.library/GetVNCPrefs NAME GetVNCPrefs - read the global preferences database SYNOPSIS size = GetVNCPrefs ( buffer , size ) d0 a0 d0 ULONG GetVNCPrefs ( struct VNCPrefs * , LONG ) FUNCTION Loads the globaly active preferences of ViNCEd. These need not to be the preferences of any window active, but the prefs that will be used by default if a new window opens. INPUTS buffer - the VNCPrefs structure allocated by AllocPrefsBuffer. size - must be set to -1. RESULTS the size of the preferences structure filled in. Should be usually ignored, this call CANNOT fail. NOTES The size parameter is only provided for backwards compatibility to VNC 2.xx and below. Passing any buffer in except those allocated by AllocPrefsBuffer, or using any other size than -1 is discouraged. SEE ALSO GetVNCDefaultPrefs(), LoadPrefsFrom(), vnc/Prefs.h vnc.library/GetVNCDefaultPrefs vnc.library/GetVNCDefaultPrefs NAME GetVNCDefaultPrefs - read the factory default preferences SYNOPSIS size = GetVNCDefaultPrefs ( buffer , size ) d0 a0 d0 ULONG GetVNCDefaultPrefs ( struct VNCPrefs * , LONG ) FUNCTION Loads the factory default preferences of ViNCEd. These are the defaults ViNCEd will use if no other preferences are available. INPUTS buffer - the VNCPrefs structure allocated by AllocPrefsBuffer. size - must be set to -1. RESULTS the size of the preferences structure filled in. Should be usually ignored, this call CANNOT fail. NOTES The size parameter is only provided for backwards compatibility to VNC 2.xx and below. Passing any buffer in except those allocated by AllocPrefsBuffer, or using any other size than -1 is discouraged. SEE ALSO GetVNCPrefs(), LoadPrefsFrom(), vnc/Prefs.h vnc.library/LoadPrefsFrom vnc.library/LoadPrefsFrom NAME LoadPrefsFrom - load the preferences from an external file SYNOPSIS size = LoadPrefsFrom ( buffer, size, filename ) d0 a0 d0 a1 ULONG LoadPrefsFrom ( struct VNCPrefs * , LONG , char * ) FUNCTION Load the ViNCEd preferences from an external file and place them in a buffer. Except that, the loaded preferences are not used for anything else. INPUTS buffer - the VNCPrefs structure allocated by AllocPrefsBuffer. size - must be set to -1. filename - the name of the file to load the preferences from. RESULTS the size of the preferences structure filled in, or zero in case of a failure. A secondary result code can be obtained by IoErr() in this case. NOTES The size parameter is only provided for backwards compatibility to VNC 2.xx and below. Passing any buffer in except those allocated by AllocPrefsBuffer, or using any other size than -1 is discouraged. This routine is able to parse (and correct) all preferences structures used so far, starting with versions 1 of VNC 1.xx up to the ASCII prefs file of version 3.60. This compatibility might be removed in a future version. Not all preferences settings of older versions will be respected, however. SEE ALSO GetVNCDefaultPrefs(), GetVNCPrefs(), IoErr(), vnc/Prefs.h vnc.library/SavePrefs vnc.library/SavePrefs NAME SavePrefs - save the preferences to the default location SYNOPSIS success = SavePrefs ( buffer , size ) d0 a0 d0 LONG SavePrefs ( struct VNCPrefs * , LONG ) FUNCTION Save the ViNCEd preferences to the default location in the ENVARC: drawer. This DOES NOT mean that the preferences become active. Hence, this does NOT include the UsePrefs() function. INPUTS buffer - the VNCPrefs structure allocated by AllocPrefsBuffer and filled in by you. size - must be set to -1. RESULTS a boolean success/failure indicator. A secondary result code can be obtained by IoErr() in case of failure. NOTES The size parameter is only provided for backwards compatibility to VNC 2.xx and below. Passing any buffer in except those allocated by AllocPrefsBuffer, or using any other size than -1 is discouraged. This routine will always save the preferences in the new ASCII format 3.3; hence, they won't be available for older versions of ViNCEd. The location this file is saved to is ENVARC:ViNCEd.Prefs, but don't take this for granted. To read the global preferences, use the GetVNCPrefs() routine. SEE ALSO SavePrefsTo(), UsePrefs(), GetVNCPrefs(), IoErr(), vnc/Prefs.h vnc.library/SavePrefsTo vnc.library/SavePrefsTo NAME SavePrefsTo - save the preferences to a given file name SYNOPSIS success = SavePrefsTo ( buffer , size , filename ) d0 a0 d0 a1 LONG SavePrefsTo ( struct VNCPrefs * , LONG , char * ) FUNCTION Save the ViNCEd preferences to the given location. This DOES NOT mean that the preferences become active. This function does not build an icon for the preferences. INPUTS buffer - the VNCPrefs structure allocated by AllocPrefsBuffer and filled in by you. size - must be set to -1. filename - the name of the file to save the preferences under. RESULTS a boolean success/failure indicator. A secondary result code can be obtained by IoErr() in case of failure. NOTES The size parameter is only provided for backwards compatibility to VNC 2.xx and below. Passing any buffer in except those allocated by AllocPrefsBuffer, or using any other size than -1 is discouraged.

SEE ALSO UsePrefs(), SavePrefsTo(), GetVNCPrefs(), IoErr(), vnc/Prefs.h vnc.library/UsePrefs vnc.library/UsePrefs NAME UsePrefs - make the preferences globally available SYNOPSIS success = UsePrefs ( buffer , size ) d0 a0 d0 LONG UsePrefs ( struct VNCPrefs * , LONG ) FUNCTION Install the preferences in the ViNCEd global database. This DOES NOT include that the prefences are installed in all open windows. It makes the preferences only available for all windows that are about to open after the preferences have been installed. INPUTS buffer - the VNCPrefs structure allocated by AllocPrefsBuffer and filled in by you. size - must be set to -1. RESULTS Non-null for success or zero on failure. A secondary result code can be obtained by IoErr() in case of failure. NOTES The size parameter is only provided for backwards compatibility to VNC 2.xx and below. Passing any buffer in except those allocated by AllocPrefsBuffer, or using any other size than -1 is discouraged. It is not guaranteed that the preferences will be made available immediately. There might be a delay of several seconds for the new prefs to become active. This routine works differently, depending on the Os version. For Os 1.3 or below, the preferences are simply copied to the ViNCEd library base. For 2.0 or above, it saves the preferences in ENV:. It's part of the VNC supervisor task to load it from there and to make them available. Do not depend on this information, however. It's likely that the 1.3 compatibility will be removed in the 3.70 release.

INPUTS cn - A pointer to the ViNCEd main structure. Need not to be locked here. buffer - the VNCPrefs structure, allocated by AllocPrefsBuffer() and filled by you. size - must be set to -1 RESULTS zero for failure and non-zero for success.

INPUTS cn - A pointer to the ViNCEd main structure. Need not to be locked here. buffer - the VNCPrefs structure, allocated by AllocPrefsBuffer() and filled by you. size - must be set to -1 RESULTS zero for failure and non-zero for success.

SEE ALSO SetWindowPrefs(), AllocPrefsBuffer(), vnc/Prefs.h vnc.library/AllocPrefsBuffer vnc.library/AllocPrefsBuffer NAME AllocPrefsBuffer - allocate a buffer for holding prefernces. SYNOPSIS prefs = AllocPrefsBuffer ( ) d0 struct VNCPrefs * AllocPrefsBuffer ( VOID ) FUNCTION Allocate a buffer capable of holding the ViNCEd preferences. INPUTS RESULTS a pointer to a initialized struct VNCPrefs. The factory default prefs will have been filled in already. Returns NULL in case no free storage is available. NOTES This function MUST be called to allocate a buffer for holding the preferences. The size of the preferences structure has changed many times in the past, and will continue to change. This call ensures that enough memory is allocated to hold a up-to-date version of the preferences. This structure, as allocated by this function, MUST be used by all preferences related functions. SEE ALSO FreePrefsBuffer(), vnc/Prefs.h vnc.library/FreePrefsBuffer vnc.library/FreePrefsBuffer NAME FreePrefsBuffer - deallocate preferences. SYNOPSIS FreePrefsBuffer ( prefs ) a1 VOID FreePrefsBuffer ( struct VNCPrefs * ) FUNCTION Deallocate a previously allocated preferences buffer of AllocPrefsBuffer(). INPUTS prefs - a pointer to the preferences buffer allocated by AllocPrefsBuffer(). It is save to pass in NULL. RESULTS NOTES This function MUST be called to release a preferences buffer allocated by AllocVNCPrefs(). There's no other documented way of deleting this buffer. SEE ALSO AllocPrefsBuffer(), vnc/Prefs.h vnc.library/List2Prefs vnc.library/List2Prefs NAME List2Prefs - build preferences strings from list SYNOPSIS ok = List2Prefs ( cn , mlist , blist , prefs , mlen , blen d0 a5 a0 a2 a1 d0 d2 ,mnum , bnum) d1 d2 LONG List2Prefs ( struct ViNCWindow * , struct List * , struct List * , struct VNCPrefs * , UWORD , UWORD , UWORD , UWORD ) ok = List2Prefs_CN ( mlist , blist , prefs , mlen , blen d0 a0 a2 a1 d0 d2 ,mnum , bnum) d1 d2 LONG List2Prefs_CN ( struct List * , struct List * , struct VNCPrefs * , UWORD , UWORD , UWORD , UWORD ) FUNCTION Given two lists consisting of struct ViNCMacro *'s and struct ViNCButton *'s, this function fills in the macro and button settings into the preferences structure. INPUTS cn - a pointer to a struct ViNCWindow. MUST be locked with LockWindow() before calling this function. mlist - an exec style doubly linked list, filled with struct ViNCMacros *. blist - an exec style doubly linked list, filled with struct ViNCButtons *. prefs - a pointer to the preferences buffer allocated by AllocPrefsBuffer(). mlen - the maximal length of a macro, should be set to VPF_FUNCLENGTH. blen - the maximal length of a button title, should be set to VPF_SHORTLENGTH. mnum - the maximal number of macros to be filled in, should be set to VPF_MACROS. bnum - the maximal number of buttons to be filled in, should be set to VPF_MAXBUTTONS. RESULTS zero for failure or non-zero for success. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. The encoding of the strings in the preferences is somewhat un- convenient for the C author. To avoid this drawback, the list of macros and buttons can be converted to a linked list of structures containing the same information which is much easier to handle - this is done by Prefs2List(). This function reverses this process and fills in the lists back to the preferences structure. After you're done with the lists, call FreeMacroList() to get rid of them. The system macros and some system texts count also as "macros"! VPF_MACROS is therefore LARGER than ten, the number of user macros. SEE ALSO Prefs2List(), FreeMacroList(), vnc/Prefs.h, exec/lists.h vnc.library/Prefs2List vnc.library/Prefs2List NAME Prefs2List - build list of preferences strings SYNOPSIS ok = Prefs2List ( cn , mlist , blist , prefs , mlen , blen d0 a5 a0 a2 a1 d0 d2 ,mnum , bnum) d1 d2 LONG Prefs2List ( struct ViNCWindow * , struct List * , struct List * , struct VNCPrefs * , UWORD , UWORD , UWORD , UWORD ) ok = Prefs2List_CN ( mlist , blist , prefs , mlen , blen d0 a0 a2 a1 d0 d2 ,mnum , bnum) d1 d2 LONG Prefs2List_CN ( struct List * , struct List * , struct VNCPrefs * , UWORD , UWORD , UWORD , UWORD ) FUNCTION Given a ViNCEd preferences structure, this function builds two lists of the macros and buttons defined in the preferences structure for easier access. INPUTS cn - a pointer to a struct ViNCWindow. MUST be locked with LockWindow() before calling this function. mlist - an exec style doubly linked list. This list is filled in with struct ViNCMacros *'s. blist - an exec style doubly linked list. This list will be filled with struct ViNCButtons *. prefs - a pointer to the preferences buffer allocated by AllocPrefsBuffer(). mlen - the maximal length of a macro, should be set to VPF_FUNCLENGTH. The vnc.library will allocate enough space for the structures to hold strings of at least this size. blen - the maximal length of a button title, should be set to VPF_SHORTLENGTH. The vnc.library will allocate at least "mlen" bytes for the button body, and "blen" bytes for the button title. mnum - the maximal number of macros to be filled in, should be set to VPF_MACROS. bnum - the maximal number of buttons to be filled in, should be set to VPF_MAXBUTTONS. RESULTS zero for failure or non-zero for success. In case of failure, both lists will be empty and all partially allocated structures will have been deallocated already. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. The encoding of the strings in the preferences is somewhat un- convenient for the C author. To avoid this drawback, the list of macros and buttons can be converted to a linked list of structures containing the same information which is much easier to handle, as done by Prefs2List(). You're now holding struct ViNCButtons and struct ViNCMacros that can be manipulated much easier. The strings associated to these structures will be at least the specified number of bytes long, even though the actual texts might be shorter. To copy these lists back to the preferences after modification, use List2Prefs(). To After you're done with the lists, call FreeMacroList() to get rid of them.

While not a problem on a standard Amiga system, I can think of some patches where this leads to a problem. However, I currently don't see another way of doing this. Feel prepared that this routine is called MORE THAN ONCE. This might happen if the handler wasn't able to shut down in time. The details about this routine are rather messy; since this HAS TO BE asynchronous to avoid deadlocks, but on the other hand the handler task has to know when the expansion has, indeed, shut down, this problem is solved by a trick: The TAB expansion task opens a ViNCEd stream itself which will inhibit that the handler shuts down before the TAB expansion quits. On this request, the handler shuts down and, while doing so, closes this stream. If the ACTION_CLOSE packet is received by the handler, this function is called again. Furthermore, to allow the close window requester working, the open count of the ViNCWindow is incremented and decremented manually by this function, which is usually a bad thing(tm) to do. Unless you know quite a lot about these internals, it's probably not a good idea to hook in here.

However, it is likely that support for the arp.library is about to be removed in the 3.70 release of ViNCEd.

It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative TAB expansion to hook in here. It is, however, called by the library itself in case the user presses ^Z to suspend the foreground owner. Some sanity checks have already been made by the library if this function is called, but not enough. Since the ^Z feature is more or less a hack, you should check very carefully if the process of the owner can be aborted safely. Especially, the current implementation checks - ViNCEd is in shell mode - the TAB expansion supervisor is up and running - whether another suspend request is still running - the port of the last process of this owner that wrote to the ViNCEd window is still available. - whether any other I/O requests are pending. - whether this port is a valid port operating on signal basis - whether the task of this port is associated to a valid and known task in the exec list of tasks. - whether a CLI for this task is available. - whether a module is loaded for this CLI or it is non-interactive. - whether it is indeed in foreground If all this is fine, the task is temporarely removed from execution. It is the job of the TAB expansion supervisor to resceldure this task and to run a new shell. BUGS The ^Z feature is really messy, but I don't see a cleaner way of making this possible with the current shell. The ViNCEd 3.60 version implements the "Medium Mode" with which something like this should be able much more system friendly. Unfortunately, there is not yet a shell that supports it.

NOTES If the utility library is available, this function is identical to UniqueID(); hence, the number returned is even unique in a system wide context. If the utility library is not availabe, i.e. in a 1.3 environment, the vnc.library implements its own version.

NOTES this function is identical to the Stricmp() routine of the utility library if this is available. It is therefore localized if the locale library is available, too. If the utility library is NOT available, ViNCEd uses its own function; however, this happens only in Os versios 1.2 and 1.3 and it is likely that this support will be removed in the release 3.70 of ViNCEd.

INPUTS cn - a pointer to the ViNCWindow main structure. MUST be locked with LockWindow() owner - a pointer to a struct ViOwner providing the process information from - source string to - destination string, must be 256 bytes large RESULTS NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative window title expansion. It is, however, called by the library itself in case the window title must be refreshed. A hooked in replacement routine MUST truncate the output string to 256 characters (including the NUL character at the end) to avoid overrunning buffers. The output buffer is documented to be 256 characters large. The current implementation reads the strings to be expanded from the process in the owner structure, including some sanety checks to make sure the process is stable. This is somehow a hack. A future version might provide a safer method. It should be actually the matter of the shell to set the window title thru an ESC sequence - which is possible for ViNCEd - but it doesn't do this.

Selects the proper macro from the ViNCEd macro list and returns the macro body to be expanded. INPUTS cn - a ViNCEd window main structure, MUST be locked with LockWindow() owner - a pointer to the owner structure to be investigated RESULTS a character pointer to the macro body, or NULL if no macro is available for this function. In this case, an EOF should be generated to shutdown the stream. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative job control to hook in. It is, however, called by the library itself in case the user pressed the close gadget of the window or wants to shutdown the stream otherwise. A replacement routine must make some sanity checks on the owner structure to make sure that the process investigated is valid and still active. It must return a shutdown string or NULL in case an EOF should be send to the owner in question. A future shell should always receive an EOF condition and send the required string to the program itself, manually.

Requests a prompt from a running foreground shell. INPUTS cn - a pointer to the ViNCWindow structure, must be locked with LockWindow() first port - a pointer to the dos message port of the process which has been suspended owner - a pointer to the owner this process is part of RESULTS NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first. You usually DO NOT want to call this function. It is provided to allow an alternative job control to hook in. It is, however, called by the library itself in case a job gets suspended and a suspend message has to be printed. This routine checks whether a shell or a program is active in this window, and prints the suspend message only if it's a shell. A press to RETURN is simulated in this case to request a shell prompt again. A replacement routine must make some sanity checks on the owner structure to make sure that the process investigated is valid and still active. A future shell should print this message itself.

The data will be not made visible on the screen. THIS IS A LOW-LEVEL FUNCTION. YOU DO NOT WANT TO CALL IT. USE THE DOS PACKET ACTION_QUEUE INSTEAD. The only reason to call this function from are replacement routines that patch into the ViNCEd job control functions and others. INPUTS cn - a pointer to the ViNCWindow main structure, MUST be locked with LockWindow(). owner - a pointer to the owner which should receive the data. buffer - the data to be placed into its input buffer. The buffer may be released afterwards or can be even kept on the stack. size - the size of the data. RESULTS a boolean success/failure code. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive. It automatically provides the window pointer which must have been set by the link library function SetCNWindow() before. It is VERY IMPORTANT that you accessed control to the ViNCEd window to be modified with LockWindow() first.

THIS IS A LOW-LEVEL FUNCTION. YOU DO NOT WANT TO CALL IT. USE THE DOS PACKET ACTION_WRITE INSTEAD. The only reason to call this function from are replacement routines that patch into the ViNCEd job control functions and others. INPUTS cn - a pointer to the ViNCWindow main structure, MUST be locked with LockWindow(). owner - a pointer to the owner which should receive the data. Must be given since some CSI sequences are owner specific. buffer - the data to be written; may contain all ViNCEd ESC/CSI sequences. size - the size of the data. RESULTS the number of characters written. NOTES There are two forms of this function available.

SYNOPSIS ok = SendAsyncPacket ( file , type , arg1 , data , size ) d0 d1 d2 a1 a0 d0 LONG SendAsyncPacket ( BPTR , ULONG , void * , void * , ULONG ) FUNCTION Builds an async type packet and allocated memory for a buffer, copies the data into this buffer and sends the packet to ViNCEd. Returns immediately and does not wait for completion of the packet. INPUTS file - a BPTR to the file handle for communication type - the type of the packet to sent, e.g. ACTION_WRITE arg1 - the first argument to be placed into the arg1 parameter of the Packet structure. data - will be copied into a buffer and filled into the arg2 pointer of the packet. Since the data is copied, you may release the buffer immediately after calling this function size - the number of bytes in this buffer. Will be copied to arg3 of the packet. RESULTS DOSTRUE in case the packet could be delivered to ViNCEd. This DOES NOT mean that ViNCEd accepted this packet properly. DOSFALSE in case of failure. NOTES This is the asynchronous packet interface of ViNCEd. DO NOT try to roll your own async packets, use this one or AllocAsyncPacket() instead. This call is optimized to work for most packets requiring a buffer and a count, as ACTION_WRITE, ACTION_QUEUE, ACTION_PUSH, ACTION_SETLINE and others. Consult the ViNCEd guide for details. It is intrinsic to this method that you don't receive a success failure indicator for the packet send. ViNCEd will deallocate all buffers and the packet itself, and won't reply it at all. If a reply code is required, build a standard packet yourself and send to the owner port using PutMsg(), then continously call GetMsg() on your reply port for the return of this packet, as it works for all other handlers. You should, however, make sure that you send packets to the port in the file handle you received, i.e. filehandle -> fh_Type (NOT fh_Port, this is a bug in the dos.library documentation). DO NOT send packets to the port in the global DOS device list or to any other port. The proper port IS REQUIRED to identify the owner this packet comes from.

INPUTS file - a BPTR to the file handle for communication size - size of an additional data packet to be allocated with the packet. This does not include the size of the packet itself. RESULTS a struct StandardPacket or NULL in case of failure. NOTES This builds an asynchronous packet. If size is larger than zero, (stdkt + 1) points to a buffer for free use. Fill in all data as usual, BUT SET BIT 31 OF THE dp_type FIELD. This identifies an asynchronous packet. Then PutMsg() this packet to the owner port of ViNCEd and forget about it. ViNCEd will not reply it, and will deallocate the packet and the buffer after- wards. If a reply code is required, build a standard packet yourself and send to the owner port using PutMsg(), then continously call GetMsg() on your reply port for the return of this packet, as it works for all other handlers.

RESULTS The primary result code of the packet. The secondary result code can be obtained by IoErr(). NOTES This call is almost identical to DoPkt() of the dos library except that a more useful register layout is available and, therefore, all packet parameters can be defined. This function is mainly here for pre 2.0 programs where no DoPkt() function of the dos.library was available.

Even though this is an asynchronous call, all packets send to ViNCEd after this call will reach the owner in foreground mode. INPUTS flags - flags for the call. Currently, no flags are defined and this MUST be set to zero. file - a file handle to a ViNCEd stream. RESULTS DOSTRUE if successful, DOSFALSE on failure. NOTES There is no guarantee that your owner will stay in foreground if this is called.

SEE ALSO Background() vnc.library/Background vnc.library/Background NAME Background - put the owner of a stream to background SYNOPSIS ok = Background ( flags , file ) d0 d0 d1 LONG Background ( ULONG , BPTR ) FUNCTION Sends the owner associated to the dos stream to background mode. Even though this is an asynchronous call, all packets send to ViNCEd after this call will reach the owner in background mode. INPUTS flags - flags for the call. Since if the given owner is send to background, something else has to go to foreground. This is defined by the following flag: #define VINBF_SHELLONLY_BIT 0L #define VINBF_SHELLONLY_MASK (1<<0L) Send only waiting shells to foreground. If not set, all owners are considered. file - a file handle to a ViNCEd stream. RESULTS DOSTRUE if successful, DOSFALSE on failure.

INPUTS cn - a struct ViNCWindow pointer to the main window this macro came from. Need not to be locked with LockWindow(). from - source string. to - destination string. MUST be 256 characters large. RESULTS a boolean success/failure indicator. NOTES There are two forms of this function available. The first form is the "natural" library form, the second is available as a stub routine in the link libraries in the archive.

It is provided to allow an alternative macro expansion to hook in. It is, however, called by the library itself in case a macro body must be expanded. This function has a somewhat different job than SendRequestPattern(). This routine has to do the actual conversion, whereas SendRequestPattern() has to deliver a request to an external task for conversion. ViNCEd will call this function directly in case the macro body has no special characters in it, or will pass it to an external host with SendRequestPattern() in case it can't do the job alone, for example if a file requester has to be build.

INPUTS file - the filehandle to read from. NOT a DOS FileHandle. buffer - the buffer to read to. size - the number of bytes to read. In record I/O, the maximal number of characters to read, the function will stop reading as soon as a record separator is found. RESULTS the number of bytes read, or -1 in case of a failure. NOTES the buffer size is passed in d1, not in d0.

INPUTS file - the filehandle to write to. NOT a DOS FileHandle. buffer - the buffer to write from. size - the number of bytes to write. The buffer will be flushed in record I/O as soon as a record separator is found. You may specify explicitly NOT to write the primary separator (usually ASCII NUL). RESULTS the number of bytes written, or -1 in case of a failure. NOTES the buffer size is passed in d1.

INPUTS body - the body text of the requester. RESULTS NOTES This function uses the old "auto" requesters of intuition for compatibility to Os 1.2/1.3. However, it is likely that the backwards compatibility will be removed in ViNCEd version 3.70. Don't expect too much from this function, especially in a Os 1.3 environment. It will *try* to format and center the text and will break the text in several lines, enlarging the requester if required, but not much more. If the text is too long, its too long. Especially, do NOT pass in body texts longer than eight lines. The lines in the body text may be separated with LF, or LF and CR.
