NAME
     sseemmuunnlliinnkk - remove a named semaphore

SYNOPSIS
     ##iinncclluuddee <>

     int
     sseemmuunnlliinnkk(const char *name);

DESCRIPTION
     The named semaphore named name is removed.  If the semaphore is in use by
     other processes, then name is immediately disassociated with the sema-
     phore, but the semaphore itself will not be removed until all references
     to it have been closed.  Subsequent calls to sseemmooppeenn() using name will
     refer to or create a new semaphore named name.

     If successful, sseemmuunnlliinnkk() will return 0.  Otherwise, -1 is returned and
     errno is set, and the state of the semaphore is unchanged.

EERRRROORRSS
     sseemmuunnlliinnkk() succeeds unless:

     [EACCES]           Permission is denied to be remove the semaphore.

     [ENAMETOOLONG]     name exceeded SEMNAMELEN characters.

     [ENOENT]           The named semaphore does not exist.
