shm_unlink(3RT) 					    Realtime Library Functions						   shm_unlink(3RT)

NAME
       shm_unlink - remove a shared memory object

SYNOPSIS
       cc [ flag... ] file... -lrt [ library... ]
       #include <sys/mman.h>

       int shm_unlink(const char *name);

DESCRIPTION
       The shm_unlink() function 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 is removed before shm_unlink() returns, but the removal of the memory
       object contents will be postponed until all open and mapped references to the shared memory object have been removed.

RETURN VALUES
       Upon  successful  completion, shm_unlink() returns 0. Otherwise it returns -1 and sets errno to indicate the error condition, and the named
       shared memory object is not affected by this function call.

ERRORS
       The  shm_unlink() function will fail if:

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

       ENAMETOOLONG	       The length of the name  string  exceeds	 PATH_MAX,  or	a  pathname  component	is  longer  than   NAME_MAX  while
			       _POSIX_NO_TRUNC is in effect.

       ENOENT		       The named shared memory object does not exist.

       ENOSYS		       The shm_unlink() function is not supported by the system.

       -1 and set errno to ENOSYS.
