This function allows an FSD to release a semaphore that was previously obtained on a call to FSH_SEMREQUEST.

Syntax

FSH_SEMCLEAR(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_EXCL_ALREADY_OWNED the exclusive semaphore is already owned.
  • ERROR_PROTECTION_VIOLATION the semaphore is inaccessible.

Calling Sequence

int far pascal FSH_SEMCLEAR(pSem)

void far * pSem;

Remarks

FSH_SEMCLEAR may block.

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