This function allows an FSD to set a semaphore unconditionally.
Syntax
FSH_SEMSET(pSem)
Parameters
- pSem
- is the handle to the system semaphore or the long address of the ram semaphore.
Returns
If no error is detected, a zero error code is returned. If an error is detected, one of the following error codes is returned:
- ERROR_INTERRUPT the current thread received a signal.
- ERROR_EXCL_SEM_ALREADY_OWNED the exclusive semaphore is already owned.
- ERROR_TOO_MANY_SEM_REQUESTS there are too many semaphore requests in progress.
- ERROR_PROTECTION_VIOLATION the semaphore is inaccessible.
Calling Sequence
int far pascal FSH_SEMSET(pSem) void far * pSem;
Remarks
FSH_SEMSET may block.
- Note
- OS/2 does not validate input parameters. An FSD, therefore, should call FSH_PROBEBUF where appropriate.
