- /* SYNOPSIS */
- __AROS_LHA(struct SignalSemaphore *, sigSem, A0),
-
- /* LOCATION */
- struct ExecBase *, SysBase, 93, Exec)
-
- /* FUNCTION
- Prepares a semaphore structure for use by the exec semaphore system,
- i.e. this function must be called after allocating the semaphore and
- before using it or the semaphore functions will fail.
-
- INPUTS
- sigSem - Pointer to semaphore structure
-
- RESULT
-
- NOTES
- Semaphores are shared between the tasks that use them and must
- therefore lie in public (or at least shared) memory.
