shm_unlink(3)
NAME
  shm_unlink - Remove a shared memory object created by a call to the
  shm_open function (P1003.1b)

SYNOPSIS
  #include <sys/mman.h>

  int shm_unlink (
  const char *name);

PARAMETERS
  *name	  Points to a name naming the shared memory object.

DESCRIPTION
  The shm_unlink function removes the name of the shared memory object
  pointed to by name.  If this file descriptor is used by other functions,
  all references to the shared memory object are removed, but content removal
  is delayed until all open and mapped references to the shared memory object
  are removed.

RETURN VALUES
  On a successful call to the shm_unlink function, a zero is returned.
  Otherwise, a value of -1 is returned and errno is set to indicate the
  error.

ERRORS
  The shm_unlink function fails under the following conditions:

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

  [ENAMETOOLONG]      The length of the name argument 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.
