FSH_SEMCLEAR - Clear a semaphore

Purpose   

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

Calling Sequence   

int far pascal FSH_SEMCLEAR(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: 

oERROR_EXCL_ALREADY_OWNED 
the exclusive semaphore is already owned. 

oERROR_PROTECTION_VIOLATION 
the semaphore is inaccessible. 
  

Remarks   

FSH_SEMCLEAR may block. 

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