Example

This example requests a FS RAM semaphore and then clears it.

#define INCL_DOSSEMAPHORES

#define NOT_OWNED 0
#define START 0
#define START_LONG 0L
#define TIME_OUT 1000L

DOSFSRSEM SemStruct;
USHORT    rc;

   SemStruct.cb = sizeof(SemStruct);   /* Initialize FS Sem */
   SemStruct.pid = NOT_OWNED;
   SemStruct.tid = NOT_OWNED;
   SemStruct.cUsage = START;
   SemStruct.client = START;
   SemStruct.sem = START_LONG;

   if(!DosFSRamSemRequest(&SemStruct,         /* Address of structure */
                          TIME_OUT))          /* Timeout */
      rc = DosFSRamSemClear(&SemStruct);      /* Address of structure */
