USCLOSEPOLLSEMA(3P)					   USCLOSEPOLLSEMA(3P)

NAME
     usclosepollsema - detach a file descriptor from a pollable semaphore

C SYNOPSIS
     #include <ulocks.h>

     int usclosepollsema (usema_t *sema);

DESCRIPTION
     usclosepollsema detaches the file descriptor associated with sema.	 In
     addition to closing the caller's file descriptor, it invalidates and
     closes any file descriptors used by other processes using the same
     semaphore and in the same share group as the caller (assuming of course
     that the share group is sharing file descriptors).

     usclosepollsema will fail if one or more of the following are true:

     [EBADF]	      The file descriptor for the semaphore has somehow been
		      already invalidated.  This implies a corruption of the
		      semaphore data structure.

     [EINVAL]	      The caller isn't a registered member of the arena that
		      sema was allocated from.

DIAGNOSTICS
     Upon successful completion, 0 is returned. Otherwise, a value of -1 is
     returned and errno is set to indicate the error.
