FSH_SEMSET

Purpose

This function allows an FSD to set a semaphore unconditionally.

Calling Sequence

int far pascal FSH_SEMSET(pSem)
 
void far * pSem;

Where

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.

Remarks

FSH_SEMSET may block.

Note: OS/2 does not validate input parameters. An FSD, therefore, should call FSH_PROBEBUF where appropriate.
