WHAT'S NEW IN REVISION 2
────────────────────────
The following has been added or changed in this revision of SEMAFORE :
- Added support for wildcards. Wildcards can now be used when
semaphores are removed ('-' command) and when checking if
semaphores exist ('!', '?', '&' and '%' (new!!!) commands). Of
course it's not possible to create semaphore with a wildcard.
- Added the new % command. This command (action) behaves simular to
the & command, except that SEMAFORE will now exit with errorlevel 1
when the semaphore is NOT present.
- Added the new * command. This command only creates the semaphore
file when it not present already (no touch). When the semaphore is
created, SEMAFORE will exit with errorlevel 1. This is useful when
you want to make sure, it's the current task which creates the
semaphore file.
- Semaphore files are now handled in Read/Write, Deny-None mode.
- Added support for the FDOPT environment variable as used by
FrontDoor. SEMAFORE supports the following options : NOCOMMIT,
FORCEINT28, NOMULD and NORES. These options can only be given via
the FDOPT environment variable and not on the command line.
- SEMAFORE will now commit all modification of semaphore files to
disk before closing the semaphore file. This can be disabled with
the NOCOMMIT option (FDOPT environment variable).
- Added support for the INT 28 timeslice return mechanism supported
by OS/2 and Windows. By default SEMAFORE uses the DPMI mechanism
(FDOPT=FORCEDPMI) when running under OS/2 or Windows. The INT 28
mechanism can be enabled by using FDOPT=FORCEINT28.
- SEMAFORE's automatic multitasker detection can now be disabled with
FDOPT=NOMULD. Only usefull when you experience problems with
multitaskers.
- Added support for true-pathnames (e.g. \\SERVER\SYS etc...).
SEMAFORE will accept them on the commandline, and will also
translate the name of network/CD drives to this true-pathname. When
NORES is included in the FDOPT environment variable, no
true-pathname translation is done.
New suggestions are welcome. See SEMAFORE.DOC on how to contact me.
