Hi All,
I'm involved in migrating an OS/2 system to Linux, which involves applications as well as drivers.
I have some doubts/questions on implementing asynchronous, repeated-interval timer mechanism with semaphore support. I meant porting Event Semaphores available in OS/2 to Linux. (DosCreateEventSem,DosWaitEventSem,DosResetEventSem,DosPostEventSem)
My need is to have semaphores which will be signalled (posted) repeated-interval timer mechanis asynchronously. In other words, I need to implement asynchronous, repeated-interval timer mechanism with semaphore support.
We thought of using condition variable (pthread_cond_init, etc..) and mutex combination to achieve this.
But it seems pthread's mutex and condition variable synchronization calls are off limits. pthread mutex-locking routines are not asynchronous signal safe.
It would be helpful, if I could get to know on how to achieve this event semaphore mechanism in Linux.
Have a nice time.
Warm Regards Arun
