Hi, I am having troubles with porting Semaphores in a project under Linux. Under Windows everything works fine, but under Linux my app keeps freezing.
The project is tiOPF v2 (TechInsite Object Persistent Framework). There is a class called TtiPool, that handles a pool of database connections. When I run the Unit Tests and create a single Lock and the Unlock it, all works fine. If I then iterrate that test by creating 10 locks and then call unlock 10 times, the Unit Tests freeze on the following line with the second iteration: if sem_wait(FSemaphore) <> 0 then raise EtiOPFInternalException.Create(cErrorTimedOutWaitingForSemaphore); * Under Linux, I am using the "pthreads" unit. What is the difference between the cthreads and pthreads unit? * The calls I am using from pthreads are: * sem_init() to create a semaphore * sem_wait() to lock the semaphore * sem_post() to unlock the semaphore All the above with a variable of type TSemaphore. Now, I have to admit, I don't know much about Semaphore's... Anybody know of some good documentation or tutorial on the net? Anything obvious I could be doing wrong?
