NAME
       shm_unlink - unlink a shared memory object

SYNOPSIS
DESCRIPTION
       The  system  call removes the name of the shared memory object named by
       the string pointed to by name.  If one or more references to the shared
       memory  object  exists  when  the  object is unlinked, the name will be
       removed before returns, but the removal of the memory  object  contents
       will  be postponed until all open and map references to the shared mem‐
       ory object have been removed.

RETURN VALUE
       returns the following values:

	      Successful completion.

	      Failure,
		   is set to indicate the error.

       If fails, is set to one of the following values:

	      [EACCES]	     Permission to  unlink  the	 named	shared	memory
			     object is denied.

	      [ENAMETOOLONG] The  length  of  the  name	 string exceeds or the
			     length of a  (pathname)  component	 of  the  name
			     string exceeds while is in effect.

	      [ENOENT]	     The named shared memory object does not exist.

	      [ENOSYS]	     is not supported by the implementation.
