UNLINK(2)                                               UNLINK(2)

     NAME
          unlink - remove directory entry

     SYNOPSIS
          unlink(name)
          char *name;

     DESCRIPTION
          Name points to a null-terminated string.  Unlink removes the
          entry for the file pointed to by name from its directory.
          If this entry was the last link to the file, the contents of
          the file are freed and the file is destroyed.  If, however,
          the file was open in any process, the actual destruction is
          delayed until it is closed, even though the directory entry
          has disappeared.

     SEE ALSO
          rm(1), link(2)

     DIAGNOSTICS
          Zero is normally returned; -1 indicates that the file does
          not exist, that its directory cannot be written, or that the
          file contains pure procedure text that is currently in use.
          Write permission is not required on the file itself.  It is
          also illegal to unlink a directory (except for the super-
          user).
