FSH_SEMWAIT - Wait for clear
This function allows an FSD to wait for an event. The event is signaled by
a call to FSH_SEMCLEAR.
int far pascal FSH_SEMWAIT(pSem, cmsTimeout)
void far * pSem;
unsigned long cmsTimeout;
pSem is the handle to the system semaphore or the long address of the ram
cmsTimeout is the number of milliseconds to wait.
If no error is detected, a zero error code is returned. If an error is
detected, one of the following error codes is returned:
the time-out expired without gaining access to the semaphore.
the current thread received a signal.
the semaphore is inaccessible.
The caller may return after the time-out period has expired without
receiving an ERROR_SEM_TIMEOUT. Semaphore time-out values, therefore,
should not be used for exact timing and sequence.
FSH_SEMWAIT may block.
Note: OS/2 does not validate input parameters. An FSD, therefore, should
call FSH_PROBEBUF where appropriate.
