│░░░░░░░░ PROBOARD SOFTWARE DEVELOPMENT KIT VERSION 2.00 ░░░░░░░░░░│
╘══════════════════════════════════════════════════════════════════╛
Included with ProBoard is a C library that allows you to write
your own extensions to ProBoard in C or C++. All you need is an
ANSI-compatible C or C++ compiler. The programs you create can be
run within ProBoard by executing a new menu function.
The ProBoard SDK files included with ProBoard are free software,
so anyone who does not use ProBoard to run a BBS on a regular
basis, but wants to write extension files, is allowed to do so
without registering ProBoard. You can distribute any ProBoard
extension files (PEX files) royalty-free. As far as we are
concerned, any program you develop with the ProBoard SDK is your
property.
┌──────────────────────────────────────────────────────────────────┐
│ Requirements │
└──────────────────────────────────────────────────────────────────┘
To create your own programs you need:
- An ANSI compatible C or C++ compiler. Compilers known to be
compatible with the ProBoard SDK are:
- Zortech C/C++ 2.0 - 3.0
- Microsoft C/C++ 5.1 - 7.0
- Borland C++ 2.0 - 3.1
- Turbo C++ 1.0
- Turbo C 1.0 - 2.0
Other compilers may work too, but were not tested.
- An MS-compatible linker (usually the one that came with your
compiler).
Linkers known to work with the ProBoard SDK are:
- All Microsoft Linkers (LINK.EXE)
- Borland's Turbo Link (TLINK)
- Zortech's BLINK
- The ProBoard SDK include file PB_SDK.H
- The ProBoard SDK library PB_SDK.LIB (for non-Borland compilers)
- The ProBoard SDK file PB_SDK.OBJ (for Borland 3.x compilers)
- 1 -
┌──────────────────────────────────────────────────────────────────┐
│ Creating ProBoard Executables (PEX-files) │
└──────────────────────────────────────────────────────────────────┘
To create your own ProBoard executable (.PEX file), you first
create a source file, say MYPROG.C. When ProBoard loads a PEX
file, it executes the function main() in your program. This
function is defined as:
void
main(int argc,char *argv[])
{
...
}
The parameters 'argc' & 'argv' contain optional data that can be
given to your program at load time (exactly like C's argc and argv
parameters). Creating this main() function is the only thing you
need to do to write a valid ProBoard executable. From this point
on, it's just like writing a regular C program. Most of the ANSI
standard library functions are available, plus many ProBoard-
specific functions and global variables, used for interfacing
between your program and the ProBoard environment. As in a regular
executable, you can build your program from several source files.
This is a tiny sample ProBoard program:
#include "pb_sdk.h"
void
main()
{
printf("You have %d minutes left.\n",TimeLeft());
AddTime(10);
printf("Now you have %d minutes left.\n",TimeLeft());
}
Included with ProBoard are a few example programs (in source form
of course).

┌──────────────────────────────────────────────────────────────────┐
│ Compiling and Linking │
└──────────────────────────────────────────────────────────────────┘
ProBoard executables have to be compiled using the LARGE memory
model.
For example (Turbo C++) : tcc -c -ml myprog.c
Once you have your .OBJ file (in this case MYPROG.OBJ), you have
to link it with the ProBoard SDK library (PB_SDK.LIB). You have to
specify a filename as output filename. The linked executable must
have extension .PEX. It is important to disable linking of the
default compiler libraries!! It is also required to turn on
case sensitivity.
e.g. Turbo C++ : TLINK MYPROG,MYPROG.PEX,,PB_SDK /N /C
Microsoft : LINK MYPROG,MYPROG.PEX,,PB_SDK /NOD /NOI;
Zortech : BLINK MYPROG,MYPROG.PEX,,PB_SDK /NOD /NOI;
That's all there is to it. Now you can run your program through
ProBoard's menu function 60.
I will now give the compiler syntax for some popular compilers:
Zortech C/C++ : ztc -c -a -ml myprog.c
Microsoft C : cl -Zep -Gs -c -AL myprog.c
Turbo C/C++ : tcc -c -ml myprog.c
Borland C++ : bcc -c -ml myprog.c
And linker syntax:
Borland : TLINK PB_SDK MYPROG,MYPROG.PEX /N /C
Microsoft : LINK MYPROG,MYPROG.PEX,,PB_SDK /NOD /NOI;
Zortech : BLINK MYPROG,MYPROG.PEX,,PB_SDK /NOD /NOI;
Note that the syntax for Borland C++ has changed from the previous
versions of the SDK. It is required that you specify PB_SDK.OBJ
BEFORE your object files, and don't link PB_SDK.LIB.
┌──────────────────────────────────────────────────────────────────┐
│ Restrictions │
└──────────────────────────────────────────────────────────────────┘
There are few restrictions in writing ProBoard executables. For C
programs there are actually only two major restriction: long math
& floating point operations.
- 3 -
Due to the fact that all compilers generate function calls to
multiply, divide and shift long integers, and that every compiler
vendor uses its own array of functions, it is impossible to
include these functions in the ProBoard SDK. As a result, it is
not directly possible to perform these operations on long values
(eg. long1 = long2 * long3). However, we did include functions to
perform these operations, but you will have to call these
functions explicitly (eg. long1 = l_mul(long2,long3)). People who
know their compiler well, can work around this problem by
extracting the long math functions from the standard library, and
linking them with the PEX file. For example, the long math
functions used by the Zortech compiler are in the module
LMATH.OBJ, located in the library ZLC.LIB. Extracting this module
is as simple as : ZORLIB ZLS *LMATH;
These are the ProBoard long math functions that you can use:
long l_mul(long1,long2) Multiply 2 long values = long1 * long2
long l_div(long1,long2) Divide 2 long values = long1 / long2
long l_mod(long1,long2) Modulo of 2 long values = long1 % long2
long l_shl(long1,int1) Left shift a long value = long1 << int1
long l_shr(long1,int1) Right shift a long value = long1 >> int1
The functions l_div(), l_mod(), l_shl() and l_shr() are also
available for unsigned long values: ul_div(), ul_mod(), ul_shl()
and ul_shr().
Floating point operations are NOT supported. So it is not possible
to use 'double' and 'float' variables & constants.
- 4 -
Another major restriction only affects C++ programs that are
compiled with some other compiler than Borland C/C++ 3.x or
Zortech C++ 3.0. In a ProBoard C++ program that is not compiled
with one of the compilers mentioned, you can't declare global
variables that have constructors or destructors (ie. no static
constructors & destructors). So this will compile fine, but will
certainly crash your machine:
class myclass
{
int a;
public:
x() { .... some action .... }
~x() { .... some action .... }
};
myclass some_global_object;
main()
{
...
}
You can, however, use objects with constructors and destructors,
as long as they are declared within a function. So this would
work:
main()
{
myclass some_local_object;
....
}
┌──────────────────────────────────────────────────────────────────┐
│ Library functions supported │
└──────────────────────────────────────────────────────────────────┘
Almost all standard library functions are supported. Note that all
functions that write to the standard output device (printf,
putchar,...) write their output to the ProBoard window and to the
user (through the modem). Functions that read from the standard
input device and from the keyboard are NOT supported.
(scanf,getch,gets,...) We provide substitutes for these functions.

For information on these functions, consult your compiler's
library reference manual.
In the string output functions (printf and puts), you can use the
following control codes in your string:
\001 or \x01 Set output color to red
:::: ::::
:::: ::::
\007 or \x07 Set output color to white
\x11 to \x17 Same as \1 to \7, but blinking colors
\t Stops output of string until user presses [Enter]
\f Clears the user's screen (if enabled in the user's
record)
NOTE: Do NOT include any standard include files from your
compiler. The only include file you can use is PB_SDK.H.
THAT'S IT!!

ScanKey() function).
──────────────────────────────────────────────────────────────────
void AddTime(int min);
──────────────────────────────────────────────────────────────────
Adds 'min' minutes to the user's time left. If 'min' is negative,
the number of minutes will be subtracted from the time left.

recalculates all limits (time,download,...).
──────────────────────────────────────────────────────────────────
void MsgEd(void);
──────────────────────────────────────────────────────────────────
Fires up the internal message editor or the fullscreen editor,
depending on the settings of the user. The message will be stored
in the file MSGTMP in the current directory. If a message is
aborted, the file MSGTMP will be deleted by the message editor.
If you create a MSGTMP file before invoking the message editor,
this file will be used as a 'quote' message.

attach = TRUE for a file attach message
crash = TRUE if this message is a crashmail message
kill = TRUE if the message has to be deleted after it is
sent
- 9 -
FIDO_NODE is a structure with the following fields:
struct
{
unsigned zone; /* Zone number */
unsigned net; /* Net number */
unsigned node; /* Node number */
unsigned point; /* Point number */
}
No checking is performed on any of the parameters!
Return value: -1 on error
0 if ok
──────────────────────────────────────────────────────────────────
bool ReadMsgArea(int area,MSGAREA *ma);
──────────────────────────────────────────────────────────────────
Reads data about a message area.
area = Message area number (1-200)
ma = Pointer to a MSGAREA structure to be filled
Check the file PB_SDK.H for details about the MSGAREA structure
definition.
Return value: FALSE if not defined
TRUE if read ok
──────────────────────────────────────────────────────────────────
bool ReadMessage(MESSAGE *msg,int msgnum);
──────────────────────────────────────────────────────────────────
Reads message id <msgid> into the MESSAGE structure. To access the
text of the message, use the function CreateMessageText().
See the file PB_SDK.H for a description of the MESSAGE structure.
Return value: FALSE if the message does not exists
TRUE if the message is read ok
- 10 -
──────────────────────────────────────────────────────────────────
void WriteMSGTMP(char *text);
──────────────────────────────────────────────────────────────────
Writes the string <text> to the file MSGTMP. The file is always
recreated when using this function. To append text to MSGTMP,
use the function AppendMSGTMP(). You have to insert your own CR/LF
pairs in the text if you want to force a newline. Lines can be
longer than 80 characters. The message processing functions will
do a word-wrap if necessary. Do NOT insert a single CR or LF in
the text. (\r or \n).
──────────────────────────────────────────────────────────────────
void AppendMSGTMP(char *text);
──────────────────────────────────────────────────────────────────
Same as WriteMSGTMP(), but adds text to an EXISTING file.
──────────────────────────────────────────────────────────────────
void ShowMessage(MESSAGE *msg);
──────────────────────────────────────────────────────────────────
Shows the message <msg> to the user, including header and message
text.
See the file PB_SDK.H for an description of the MESSAGE structure.
──────────────────────────────────────────────────────────────────
void CreateMessageText(MESSAGE *msg);
──────────────────────────────────────────────────────────────────
Reads the text that belongs to message <msg>, and stores it in a
file called MSGTMP in the current directory. This file can then be
accessed as an ordinary textfile.
──────────────────────────────────────────────────────────────────
void CreateMessageTextString(MESSAGE *msg,char *text,int max);
──────────────────────────────────────────────────────────────────
Reads the text that belongs to message <msg>, and stores it in the
string <text>. The text will be terminated by a '\0' character.
You have to specify a maximum number of characters that can be
stored in <text>.
- 11 -
──────────────────────────────────────────────────────────────────
bool FirstMessage(MESSAGE *msg,int area,int order,long first);
bool NextMessage(MESSAGE *msg,int area,int order);
──────────────────────────────────────────────────────────────────
These functions are used to read messages in forward or reverse
order. To start scanning messages, you have to call the
FirstMessage() function first, and the NextMessage() function to
read more messages.
msg = MESSAGE structure where the message has to be stored.
area = area number to read messages in (0 = all areas)
order = 1 for forward order, -1 for reverse order
first = message to start reading from. This message does NOT
need to exist. The first non-deleted message following
this message will be read first.
See the file PB_SDK.H for an description of the MESSAGE structure.
Return value: FALSE No more messages found.
TRUE Message was found and read ok.
This is an example on how to use these functions:
result = FirstMessage(msg,0,+1,1);
while(result == TRUE)
{
/* Do something with the message */
result = NextMessage(msg,0,+1);
}
──────────────────────────────────────────────────────────────────
void DeleteMessage(MESSAGE *msg);
──────────────────────────────────────────────────────────────────
Deletes message <msg>.
──────────────────────────────────────────────────────────────────
void MarkMessage(long msgid);
──────────────────────────────────────────────────────────────────
Marks message <msgid> for later retrieval. Up to 200 messages can
be marked.
- 12 -
──────────────────────────────────────────────────────────────────
void ReadMarkedMessages(void);
──────────────────────────────────────────────────────────────────
Shows all marked messages to the user, with the option to wait
after each message. If the user selected to wait after each
message, the standard message options menu will be shown to the
user. (Next,Prev,Stop,...).
In fact, this function is identical to menu function "Read
Messages", with the user selecting "Marked".
──────────────────────────────────────────────────────────────────
void ListMarkedMessages(void);
──────────────────────────────────────────────────────────────────
Is similar to ReadMarkedMessages(), but this function acts as a
"QuickScan Messages" with the user selecting "Marked".
──────────────────────────────────────────────────────────────────
void UnMarkAllMessages(void);
──────────────────────────────────────────────────────────────────
Unmarks all messages that were previously marked. You have to call
this function before marking any messages, because the list of
marked messages is remembered until a user logs off.
──────────────────────────────────────────────────────────────────
int NumMsgAreas(void);
──────────────────────────────────────────────────────────────────
Returns the highest message area number that is not empty.
──────────────────────────────────────────────────────────────────
long GetLastRead(int areanum , long user_recno);
void SetLastRead(int areanum , long user_recno , long msgid);
──────────────────────────────────────────────────────────────────
Reads / Sets the lastread pointer for a specific user and message
area. If GetLastRead() returns -1, an error occurred.
- 13 -
<areanum> ..... The area number (1-10000)
<user_recno> .. The record number of the user (0 - ...)
<msgnum> ...... The id of the message you want to set the
lastread pointer to.
──────────────────────────────────────────────────────────────────
int FuzzySearch(char *text,char *string,int degree);
──────────────────────────────────────────────────────────────────
Performs a fuzzy search for <string> in <text>. <degree> is the
percentage of the characters in <string> that have to match.
Return value: -1 if not found
>0 percentage of characters matched
──────────────────────────────────────────────────────────────────
IO_... functions
──────────────────────────────────────────────────────────────────
All functions starting with IO_ are low-level functions to access
the serial port directly. Do NOT use these functions for ordinary
I/O operations. They are intended for writing file transfer
protocols. See the file PB_SDK.H for a description of these
functions.
──────────────────────────────────────────────────────────────────
char WaitKey(void);
──────────────────────────────────────────────────────────────────
Waits for a character to be read from the modem or local keyboard.
Return value: the character read.
- 14 -
──────────────────────────────────────────────────────────────────
char WaitKeys(char *keylist);
──────────────────────────────────────────────────────────────────
Waits for any character specified in <keylist>.
Return value: the key from the list that was pressed (converted to
uppercase if the key is a letter).
Example : c = WaitKeys("ABC\r\x1b");
/* Waits for A,B,C,<Enter> or <Esc> */
──────────────────────────────────────────────────────────────────
void Input(char *buf,int len,int readmode);
──────────────────────────────────────────────────────────────────
Asks for a string from the user. The string is stored in <buf>,
and the user will not be allowed to enter more than <len>
characters.
<readmode> : INPUT_ALL : All characters are allowed
INPUT_UPFIRST : First character of each word is
converted to uppercase.
INPUT_UPALL : All characters are converted to
uppercase.
INPUT_DIGITS : Only digits are accepted.
INPUT_NOFIELD : OR together with any of the
previous modes if you don't want an
input-field background to be
displayed.
──────────────────────────────────────────────────────────────────
bool Ask(bool default);
──────────────────────────────────────────────────────────────────
Asks for a Yes or No response from the user. Pressing 'Y' returns
TRUE and outputs "Yes". Pressing 'N' returns FALSE and sends "No"
to the user. Pressing <Enter> returns <default>, and sends "Yes"
or "No", depending on <default>.
- 15 -
──────────────────────────────────────────────────────────────────
char PeekChar(void);
──────────────────────────────────────────────────────────────────
Checks if a character is available in the input buffer, and
returns that character if there is.
Return value: 0 if no character available
!= 0 the character read (key pressed by user)
──────────────────────────────────────────────────────────────────
void SetColor(char color);
──────────────────────────────────────────────────────────────────
Changes the current output color. All text that is output after
this function is called will be displayed in the specified color.
This function does nothing when the user does not have ANSI or
AVATAR enabled.
<color> can be one of the following:
BLACK , RED , GREEN , YELLOW , MAGENTA , BLUE , CYAN , WHITE
──────────────────────────────────────────────────────────────────
void SetfullColor(unsigned char color);
──────────────────────────────────────────────────────────────────
Changes the current foreground & background color. The color code
is an IBM-type screen color code. This function does nothing when
the user does not have ANSI or AVATAR enabled.
Some examples:
0x1E : Bright yellow on dark blue background.
0x87 : Blinking white on a black background.
──────────────────────────────────────────────────────────────────
void GotoXY(int x,int y);
──────────────────────────────────────────────────────────────────
Moves the cursor to position (x,y). The upper left corner of the
screen is (1,1). This function does nothing when the user does
not have ANSI or AVATAR enabled.
- 16 -
──────────────────────────────────────────────────────────────────
void ClrEol();
──────────────────────────────────────────────────────────────────
Clears from the current cursor position to the end of the
line. This function does nothing when the user does not have ANSI
or AVATAR enabled.
──────────────────────────────────────────────────────────────────
void EnableStop(void);
void DisableStop(void);
bool Stopped(void);
──────────────────────────────────────────────────────────────────
Enables stopping of output by pressing 'S'. When enabled, a user
can press 'S' to stop incoming text. When this happens, any
string output function will immediately return to the caller, en
the function Stopped() will return TRUE to indicate that the user
requested to stop output.
EnableStop() Enables this feature and sets the "stopped"
status to FALSE .
DisableStop() Disables the stop feature.
Stopped() Returns the "stopped" flag (TRUE or FALSE).
Example:
EnableStop();
for(i=0;i<100;i++)
{
printf("...something...");
if(Stopped()) break;
}
- 17 -
──────────────────────────────────────────────────────────────────
char ShowHotkeyFile(char *filename,char *hotkeys);
──────────────────────────────────────────────────────────────────
Shows the file <filename> to the user, and watches for incoming
keys that are specified in <hotkeys>. If one of these keys is
detected, the function stops output, and returns the hotkey. The
"stop" feature will be enabled when sending the file.
Return value: 0 : File sent completely and no hotkeys pressed.
1 : 'S' pressed (output stopped)
2 : File not found
!=2 : Hotkey detected
──────────────────────────────────────────────────────────────────
char ShowHotkeyANSIFile(char *filename,char *hotkeys);
──────────────────────────────────────────────────────────────────
This function is identical to ShowKotkeyFile(), except for the
fact that no extension and path can be specified. Depending on the
setting of the user, <filename>.ANS/ASC in the textfiles
directory will be sent. If no .ANS file is found, it will try to
send the .ASC file. If that fails too, 2 will be returned.
Return value: 0 : File sent completely and no hotkeys pressed.
1 : 'S' pressed (output stopped)
2 : File not found
!=2 : Hotkey detected
──────────────────────────────────────────────────────────────────
void InitLineCounter(void);
bool LineCounter(void);
──────────────────────────────────────────────────────────────────
These functions are used to support page pausing ("More Y/N").
Calling InitLineCounter() initializes the line counter to 0.
Every time you call LineCounter(), the line counter is incremented
by one. If the counter reaches the screen length, the user will be
asked if he wants to continue reading. If he selects "No", the
LineCounter() function will return FALSE.
- 18 -
Example:
InitLineCounter();
for(;;)
{
printf("...something...\n");
if(!LineCounter()) break;
}
──────────────────────────────────────────────────────────────────
bool ExternalInput(void);
──────────────────────────────────────────────────────────────────
Returns TRUE when the last character that was read through any of
the input routings originated from the remote keyboard (ie. the
sysop did not type it).
──────────────────────────────────────────────────────────────────
int ReadUser(USER_REC *rec,int recnr);
──────────────────────────────────────────────────────────────────
Reads user record number <recnr> (0-...) from the user file and
stores it in <rec>.
Return value: -1 if record does not exist.
0 if record is read ok.
──────────────────────────────────────────────────────────────────
void WriteUser(USER_REC *rec,int recnr);
──────────────────────────────────────────────────────────────────
Writes user record <rec> to record number <recnr> in the userfile.
- 19 -
──────────────────────────────────────────────────────────────────
char PlayMusic(char *filename,char *hotkeys);
──────────────────────────────────────────────────────────────────
Plays a .MUS file. The file has to be located in the ProBoard
system directory. Do not include a path and extension in
<filename>. The music can be stopped if the sysop presses one of
the keys specified in <hotkeys>. ^^^^^
Return value: 0 Music file played till the end
1 Music file not found
>1 The hotkey pressed by the SYSOP
^^^^^
──────────────────────────────────────────────────────────────────
void PostInfo(char *filename);
──────────────────────────────────────────────────────────────────
Does exactly the same as the POSTINFO statement in a .Q-A file.
No path and extension is allowed in <filename>. The file where
the information will be written to will have the extension .ASW
and will be placed in the ProBoard system directory.
──────────────────────────────────────────────────────────────────
int ReadFileArea(int areanum,FILEAREA *fa);
──────────────────────────────────────────────────────────────────
Reads information about file area number <areanum> in the <fa>
structure.
Check the file PB_SDK.H for details about the FILEAREA structure.
Return value: -1 File area does not exist
0 Ok
──────────────────────────────────────────────────────────────────
void MenuFunction(int function,char *data);
──────────────────────────────────────────────────────────────────
Executes menu function <function> with <data>. For details, see
the menu functions description in this file.
There are named constants declared for each function in the file
PB_SDK.H. It is recommended that you use these constants instead
of numbers.

──────────────────────────────────────────────────────────────────
void Log(int loglevel,char *fmt,...);
──────────────────────────────────────────────────────────────────
With this function you can write information to the ProBoard
logfile. The log entry will be written if the user has a loglevel
that is greater than <loglevel> .
<loglevel> can be one of the following:
LOG_FRIEND , LOG_NORMAL , LOG_SUSPICIOUS , LOG_DANGEROUS
If you want a log entry to be written regardless of the user's
loglevel, use LOG_FRIEND.
The Log() function works like the printf function: you can use
format specifiers in the <fmt> string, and pass extra parameters.
Example: Log(LOG_NORMAL,"User's name = %s",CurUser->name);
──────────────────────────────────────────────────────────────────
void HangUp();
──────────────────────────────────────────────────────────────────
Hangs up the phone, logging off the user. It is exactly the same
as pressing Alt-H.
──────────────────────────────────────────────────────────────────
bool CheckAccess(int level,long flags);
──────────────────────────────────────────────────────────────────
Checks if the current user can access something that requires
<level> and <flags>. Returns TRUE if the user has access, FALSE if
not.
──────────────────────────────────────────────────────────────────
KEY ScanKey(void);
──────────────────────────────────────────────────────────────────
Checks the LOCAL keyboard for a key, and returns the scan code for
that key. If no key is available, 0 will be returned.
For a list of defined values for scan codes, check the file
PB_SDK.H.

──────────────────────────────────────────────────────────────────
bool GetFlag(long flags,char flagchar);
void SetFlag(long flags,char flagchar);
void ClearFlag(long flags,char flagchar);
──────────────────────────────────────────────────────────────────
Access flags are stored in a long integer (32 bits). You have 3
macros at your disposal to manipulate access flags:
GetFlag : Returns TRUE if flag <flagchar> is set
SetFlag : Turns flag <flagchar> on
ClearFlag : Turns flag <flagchar> off
<flagchar> must be a value from 1 to 32. 1-26 correspond to A-Z,
while 27-32 are the same as 1-6.
──────────────────────────────────────────────────────────────────
int ErrorLevel(void);
──────────────────────────────────────────────────────────────────
Returns the errorlevel of the last executed shell command (Through
MenuFunction(MENU_SHELL,...))
──────────────────────────────────────────────────────────────────
bool GetIniVar(char *fname,char *varname,char *value,int max);
bool SetIniVar(char *fname,char *varname,char *value);
──────────────────────────────────────────────────────────────────
These functions can be used to read and write to .INI files. These
files are similar to the files used by MS Windows. They can be
used to store settings for your application (PEX). An example
of a .INI file:
DataPath = C:\PB\PEX\MYPEX\DATA
ProgPath = C:\PB\PEX\MYPEX
MaxUsers = 10
This is a standard ASCII file, with each line in the form
<varname> = <value>
The value of a specific variable can be read by calling the
function GetIniVar(). Setting a variable (writing to the .INI file
or createing it if it doesn't exist yet) can be done by calling
SetIniVar().
The parameters for the functions are:
- 22 -
<fname> Name of the .INI file. The extension of the file
will always be changed to .INI by ProBoard.
<varname> Name of the variable (case INsensitive)
<value> For GetIniVar() : a pointer to a buffer where the
variable's contents will be
stored.
For SetIniVar() : a pointer to the value of the
variable.
<max> Maximum number of characters that can be copied
in <value> (including trailing '\0')
Return value: FALSE if the file could not be opened or the
variable does not exist.
──────────────────────────────────────────────────────────────────
void exit(void);
──────────────────────────────────────────────────────────────────
Exits the current pex-program, and unloads it from memory.
──────────────────────────────────────────────────────────────────
void ExitTSR(void);
──────────────────────────────────────────────────────────────────
Exits the current pex-program, and leaves it resident. This has
some important implications:
- All global and static variables keep their values for
subsequent executions.
- When the same pex-file is run again through menu function 60,
the resident copy will be executed. This will result in faster
loading.
- Any handlers that were installed will be called.
- 23 -
──────────────────────────────────────────────────────────────────
void InstallHandler(int handler,function);
──────────────────────────────────────────────────────────────────
This is probably the most advanced and complicated function in the
ProBoard SDK. With this function you can set up a "handler" for a
specific action. Right now, only two types of handlers are
supported: a replacement for the sysopkey-handler and a handler
to intercept loss of carrier. This way you can create your own
sysopkeys, or change the behaviour of existing sysopkeys. You could
create a handler that intercepts the Alt-J key, and write your own
flavor. In future versions you will be able to set up handlers for
low-level I/O operations. So you could replace all I/O routines by
your own functions. This way you can support your own exotic
hardware or something like that. Anything goes!
handler : Handler type. At this time, only HANDLER_SYSOPKEY
and HANDLER_HANGUP are supported.
function : A pointer to the handler function you created.
You can install as many handlers as you want. When the PEX is
removed from memory (when the PEX exits), all handlers that were
installed will be removed by ProBoard.
The handler function is a function that returns an integer. The
parameters depend on the type of handler you are creating.
For HANDLER_SYSOPKEY the handler function has to be declared like
this:
int sysopkeyhandler(KEY k)
{
...
}
A sysopkey handler intercepts any special key that is pressed by the
sysop. (like F1,Alt-H,...). You can redefine any key, or add your
own.
- 24 -
For HANDLER_HANGUP, the handler functions has to be declared like
this:
int hanguphandler(void)
{
...
}
The hangup handler works a little different: it is called whenever
ProBoard exits (carrier lost, sysop hung up,...). It can be used to
perform some cleanup for your running PEX file (like closing
files, writing data, etc..). You can install the handler at the
start of your program and remove it before the program is
finished.
If a handler function decides to do anything, it has to return
HANDLED. If the handler wants to leave it up to ProBoard, it must
return NOT_HANDLED.
This asks for an example I suppose:
int keyhandler(KEY k)
{
if(k == KEY_ALTJ)
{
printf("\7\rHang on %s! I'm shelling to DOS...",UserFirstName);
MenuFunction(MENU_SHELL,"*N*Q*X*!");
printf("I'm back!!\n");
return HANDLED;
}
else return NOT_HANDLED;
}
main(int argc,char *argv[])
{
InstallHandler(HANDLER_SYSOPKEY,keyhandler);
ExitTSR(); /* IMPORTANT */
}
So what does it do? It intercepts the sysopkey-function, and
checks if the key pressed is Alt-J. If it is, it shells to DOS
with swapping ON, and it writes its own messages to the screen.
When the sysop returns, the handler returns HANDLED to let
ProBoard know that it does not have to process the key. You could
use this example in an INIT.PEX file.
Is this powerful or what?

──────────────────────────────────────────────────────────────────
void RemoveHandler(int handler,function);
──────────────────────────────────────────────────────────────────
Removes handler number <handler> which has been installed by
InstallHandler(). <function> is the pointer to the handler that
should be removed.
──────────────────────────────────────────────────────────────────
int ReadHandler(int handler, HANDLER *hnd);
──────────────────────────────────────────────────────────────────
Saves all info about a currently installed handler function in a
structure. The handler can be restored at a later time by using
the function RestoreHandler(). 'handler' is the number of the
handler that should be saved, and 'hnd' is a pointer to the
structure where the handler function should be saved.
──────────────────────────────────────────────────────────────────
long MsgNum(int area, long id)
──────────────────────────────────────────────────────────────────
Returns the message number for message 'id', in area 'area'. For
Hudson and *.MSG, this is identical to the message id (but DO NOT
rely on that). Returns a value < 1 if there is no message number
for 'id'.
──────────────────────────────────────────────────────────────────
long MsgId(int area, long n)
──────────────────────────────────────────────────────────────────
Returns the message id for message number 'n', in area 'area'. For
Hudson and *.MSG, this is identical to the message number (but DO
NOT rely on that). Returns a value < 1 if there is no message
number 'n'.
──────────────────────────────────────────────────────────────────
long HighMsg(int area)
──────────────────────────────────────────────────────────────────
Returns the message id of the last message in the given area.
Note: if the lastread pointer is higher than what this function
returns, DO NOT use FirstMessage()! The FirstMessage() function
does not support reading past the end of the area. (if you know
what I mean :-)
- 26 -
──────────────────────────────────────────────────────────────────
long NumMsgs(int area)
──────────────────────────────────────────────────────────────────
Returns the total number of messages in the given area.
──────────────────────────────────────────────────────────────────
void LocalDisplay(bool showlocal)
──────────────────────────────────────────────────────────────────
Enables/Disables local echo of text. A parameter of TRUE means
"enable local display". FALSE means "disable local display". See
_GRAPH.CPP for an example.
──────────────────────────────────────────────────────────────────
void RemoteDisplay(bool showremote)
──────────────────────────────────────────────────────────────────
Enables/Disables remote echo of text. A parameter of TRUE means
"enable remote display". FALSE means "disable remote display".
See _GRAPH.CPP for an example.
──────────────────────────────────────────────────────────────────
bool RIP()
──────────────────────────────────────────────────────────────────
Returns TRUE if RIP was detected and enabled. FALSE if not...
──────────────────────────────────────────────────────────────────
void ShowRIPscrip( char *name )
──────────────────────────────────────────────────────────────────
This will send a RIP file located in the RIP directory. No file
extension should be given. (.RIP is assumed) The file will not
be shown on the local screen.

│ Global ProBoard Variables │
└──────────────────────────────────────────────────────────────────┘
You have access to some important ProBoard system variables
through global variables defined in PB_SDK.H.
──────────────────────────────────────────────────────────────────
word PBVersion;
──────────────────────────────────────────────────────────────────
The version number of ProBoard. The high byte is the major version
number (eg. 1). The low byte is the minor version number in
hex (eg. 0x30). So if you're using ProBoard v1.30, PBVersion will
be set to 0x0130 .
──────────────────────────────────────────────────────────────────
word Beta;
──────────────────────────────────────────────────────────────────
The beta version number of ProBoard. If this number is 0xFFFF,
it means that the release version is running. Beta numbers
start from 1.
For example, when running ProBoard 1.40 Beta/19, PBVersion will be
set to 0x0140, and Beta will be set to 19.
──────────────────────────────────────────────────────────────────
long BaudRate
──────────────────────────────────────────────────────────────────
The current bps rate of the caller. 0 means local.
- 28 -
──────────────────────────────────────────────────────────────────
USER_REC * CurUser;
──────────────────────────────────────────────────────────────────
Pointer to the current user record. You can change any of the
field values in the record, but this will not result in any
immediate action by ProBoard. For example, if you change the
user's level, ProBoard will not know that you changed it, so you
will have to tell it by calling AdjustTime();
Check the file PB_SDK.H for a description of the USER_REC
structure.
──────────────────────────────────────────────────────────────────
int UserRecNr;
──────────────────────────────────────────────────────────────────
The record number of the current user's record in the file
USERS.BBS, starting from 0. This value cannot be changed.
──────────────────────────────────────────────────────────────────
int NumLimits;
──────────────────────────────────────────────────────────────────
The number of user levels defined in ProCFG. You can access the
limit-values through the global array 'Limits'. This value
cannot be changed.
──────────────────────────────────────────────────────────────────
LIMIT * Limits;
──────────────────────────────────────────────────────────────────
Is an array of all user levels defined, with download and time
limits. Check the file PB_SDK.H for information on the LIMIT
structure.
You are not allowed to change any values! (A good compiler should
generate an error or warning if you try to do so)
- 29 -
──────────────────────────────────────────────────────────────────
char * LoginDate;
char * LoginTime;
──────────────────────────────────────────────────────────────────
This is the login date & time of the current user.

│ Special-purpose PEX-files │
└──────────────────────────────────────────────────────────────────┘
Several pex-files will be loaded automatically (if present). They
perform certain actions like edit a message, set up handlers, etc.
INIT.PEX : Will be loaded and executed before any I/O
has been done. Use this to set up any
handlers (sysopkey handlers, ...)
INIT_1.PEX -
INIT_9.PEX : Is the same as INIT.PEX, but will be loaded
in the order of the numbers. So you can have
up to 10 initialization pex-files.
LOGIN.PEX : Is run just before the user is asked for
his/her name.
BIRTHDAY.PEX : Is run after showing NEWS.ANS/ASC if today
is the user's birthday.
NEWUSER.PEX : Is run before the file NEWUSER.A?? is shown.
NEWUSER1.PEX : Is run before the file NEWUSER1.A?? is
shown.
NEWUSER2.PEX : Is run before the file NEWUSER2.ANS/ASC is
shown.
WELCOME.PEX : Is run before the file WELCOME.ANS/ASC is
shown
WELCOMEx.PEX : Is run before the file WELCOMEx.ANS/ASC is
shown (x = 1 to 9)
SECxx.PEX : Executed when a user with security level xx
logs in. Is run before SECxx.ANS/ASC is
shown.
EXPIRED.PEX : Is run before EXPIRED.ANS/ASC is shown, and
after a user's level is lowered because the
subscription date was reached. ProBoard will
send one parameter to this PEX: the original
level, before it was changed by ProBoard.
GOODBYE.PEX : Is run before GOODBYE.ANS is displayed.
GOODBYE2.PEX : Is run after GOODBYE.ANS is displayed.
- 32 -
MSGED.PEX : Is a replacement of the built-in message
editor. It will be executed with no
parameters. The message that you create has
to be written to a file called MSGTMP.
ProBoard will then read this file and create
a message from it. To let ProBoard know that
the user has aborted a message, delete
MSGTMP.
FSED.PEX : Is similar to MSGED.PEX, but will be
executed if the user has selected the
fullsrceen editor. It works the same way as
MSGED.PEX, but ProBoard will create a MSGTMP
file with the original message if a user is
replying to a message.
