- Hi,
-
- I want to use semaphores to protect critical regions in a multi tasking
- application. A problem is that these tasks are only started when an external
- event occurs (phone rings) and they are stopped by another external event
- (hang up). Is it possible to establish semaphores which stay in effect as
- long as the whole application (which consistes of sveral processes) is
- running ?
-
- Could I accomplish that by creating these semaphores in a "semaphore
- manager process" which could also fulfill a watchdog function ?
-
- Or could this kind of semaphore be created in shared memory ?
-
- This question applies to both OS/2 1.3 and OS/2 2.0.
-
-
- Thanks for any info, Ernst.
