msem_remove(3)
NAME
  msem_remove - Remove a semaphore

SYNOPSIS
  #include <sys/mman.h>

  int msem_remove(
	  msemaphore *sem );

LIBRARY
  Standard C Library (libc)

PARAMETERS
  sem Points to an msemaphore structure which specifies the semaphore to be
      removed.

DESCRIPTION
  The msem_remove() function removes a binary semaphore.  Any subsequent use
  of the msemaphore structure before it is again initialized by calling the
  msem_init() function will have undefined results.

  The msem_remove() function also causes any process waiting in the
  msem_lock() function on the removed semaphore to return with an error.

  If the msemaphore structure contains any value not resulting from a call to
  the msem_init() function followed by a (possibly empty) sequence of calls
  to the msem_lock() and msem_unlock() functions, the result is undefined.
  The address of an msemaphore structure may be significant.  If the
  msemaphore structure contains any value copied from an msemaphore structure
  at a different address, the result is undefined.

NOTES
  AES Support Level:
      Trial use

RETURN VALUES
  On successful completion, the msem_remove() function returns 0 (zero). On
  error, the msem_remove() function returns -1 and sets errno to indicate the
  error.

ERRORS
  If the msem_remove() function fails, errno may be set to the following
  value:

  [EINVAL]
      The sem parameter points to an msemaphore structure which specifies a
      semaphore which has been removed.
