NAME

       msem_remove - remove a semaphore in mapped file or anonymous region

SYNOPSIS

DESCRIPTION

       removes a binary semaphore.

       sem  points to an structure that specifies the semaphore to be removed.	Any subsequent use of the structure before it is again initialized
       by calling produces undefined results.

       also causes any process waiting in the function on the removed semaphore to return with an error.

       If the structure contains any value not resulting from a call to followed by a (possibly empty) sequence of calls to and  the  results  are
       undefined.   The address of an uniquely identifies the semaphore.  If the structure contains any value copied from a structure at a differ-
       ent address, the result is undefined.

RETURN VALUE

       Upon success, returns zero; otherwise, it returns -1 and sets to indicate the error.

ERRORS

       fails if any of the following conditions are encountered:

	      [EINVAL]	     sem points to an structure that has been removed.

	      [EFAULT]	     sem is an invalid pointer.
