Changes to the library:
August 27, 2000 (1.04)
+ Finished adding trace points (well, unless new specific problems arise that
aren't covered here...)
August 18, 2000
! Docs for RxSemListWindows had wrong function name!
+ Added SemTraceFile - tracing for some functions enabled, will be doing more
as time progresses.
August 10, 2000
! Fixed more memory leaks, and other miscellaneous well-hidden bugs.
July 26, 2000
+ Added an icon - anyone else have a better one?
July 22, 2000 (1.03)
+ Added RxSemWindowList and RxSemToggleSwitchVisibility
July 14, 2000
! Fixed a memory leak when setting REXX variables
+ Started using LXLite to compress the DLL. Chopped over 30% off its
size.
April 30, 2000
! Reference (HTML) didn't have SemEWait in its TOC... woops. Found
this while looking it up for help using it myself.
February 23, 2000 (1.02)
+ Added SetTextScreenSize so I wouldn't need to create another process
to run 'mode'.
August 19, 1999 (1.01) <release>
+ Added POSTONE and AUTORESET to SemECreate, under advice from
Scott E. Garfinkle <seg@austin.rr.com>.
July 28, 1999 (1.00) <release>
+ Added SemMQuerySemHandle, SemEQuerySemHandle, indirect request from
Daniel Hellesretin <danielh@crosslink.net>
! Claiming a mutex with a wait of zero waited forever, as if no
wait was specified. (Reported by Daniel Hellesretin
<danielh@crosslink.net>.)
July 7, 1999
+ Added ChecksumFile
June 24, 1999
+ Added MyProcessID and ChecksumString
June 20, 1999
+ Added registration codes so that I can pull this software out
of beta (finally!). Available on Hobbes. Semaphores are not
limited, only the extra miscellaneous functions, except for
opening Netscape windows.
June 16, 1999
+ Very late at night, added KillProcess. (See the reference to
see what I mean.)
June 13, 1999
+ Added PriorityQuery and PrioritySet
June 6, 1999 (0.7b) <release>
+ Added *GetAllSems because it was only about 12 lines of code,
and could be of some use to some people. This also returns back
the *name* of the semaphores.
* Changed the reference to .htm (I'm still FAT-compliant).
+ Added everything to new website: http://tower.to.org/rexxsem
+ Finished (and even debugged) event semaphores.
May 16, 1999
! Rewrote (this is too common of a word here ...) the semaphore
interface. All mutex-semaphore functions (16- and 32-bit) have
been renamed to SemM* from Sem*. This, so that I can add Event
semaphores as SemE*.
+ Started work on Event semaphores, something intended back in 1998,
but only started now 'cuz someone almost requested it.
* Changed dates in this file to be Y2K compliant. Now the entire
product is Y2K compiant, not just the code. :-)
+ Added SemMCreate which will determine if you want a 32-bit or
16-bit semaphore based on the semaphore name - whether it starts
with "\SEM32\" or "\SEM\".
Sep 04, 1998
+ Created RxWinSetTitle.
+ SemLogState changed to not create an empty file if there is
nothing to log. This will let you leave your 'debug' code in
even when nothing goes wrong.
Jun 22, 1998 (0.6b) <release>
! Something changed - first SemCreate wasn't working, next SemClose
wasn't working (as advertised anyway). Cleaned these up! Boy
am *I* glad I said this was BETA!
+ Created SemVersion to return the version info. Returns
"REXXSEM v<version>". Starts at "REXXSEM v0.6b".
Jun 21, 1998
+ Added explicit licencing information to the documentation after
request for same from Matthew Davis <prs@twave.net>
May 31, 1998 (0.5b) <release>
* Rewrote to use VAC++ rather than Watcom partly because I no longer
have Watcom installed, but do have IBM's Visual Age installed. I
hope not to have to remove VAC++ anytime soon...
+ Added language-independence. Can use other languages if someone
is willing to translate for me. This is the creation of
SemSetLanguageDll. Will ship languages in the archive as they
are created.
+ Added OpenNetscapeWindow, ProcessIDsOf, WordWrap.
* Renamed REXXSEM.TXT to REXXSEM.REF since it was really a
reference file. Created new TXT file as an overview
description.
Mar 23, 1997
! Changing the interface broke it. Would display wrong string
when had to wait for semaphore. Now displays correct string.
Mar 05, 1997 (0.4b) <release>
* Changed the interface to SemClaim to make a bit more sense.
Mar 02, 1997
+ Added optional message parameter to SemClaim. This simplifies any
user-friendly rexx coding immensely. This is what happens when...
* Author finally started using his own code. :-) Got tired of having
to code (in rexx) all the user-friendly stuff the same way, so I
cheated - I put it into the rexx code. :-)
Jan 19, 1997 (0.3b)
+ Added SemCloseAll to simplify closing all semaphores.
* Not really released.
Jan 9, 1997 (0.2b) <release>
! SemClaim returned the wrong values when using a timeout. Fixed.
(Reported indirectly by Tony Koker <74105.1432@CompuServe.COM>)
* SemClaim would "lock" if attempting to claim a second time. Now
it simply returns "CLAIMED". This is to prevent a lock in otherwise
invalid behaviour (you should not claim an already-claimed semaphore)
(Reported by Tony Koker <74105.1432@CompuServe.COM>)
* SemRelease probably returned invalid values if releasing a non-claimed
semaphore, or releasing an already-released semaphore. Don't know
what it did, but it will always return successfully now in these
cases. However, again, you should only be releasing semaphores that
are already claimed. (Reported indirectly by
Tony Koker <74105.1432@CompuServe.COM>)
