t_unbind(3N)          (Networking Support Utilities)           t_unbind(3N)


   NAME
         t_unbind - disable a transport endpoint

   SYNOPSIS
         #include <tiuser.h>

         int t_unbind (int fd);

   DESCRIPTION
         The t_unbind function disables the transport endpoint specified by fd
         which was previously bound by t_bind(3N).  On completion of this
         call, no further data or events destined for this transport endpoint
         will be accepted by the transport provider.

         On failure, t_errno may be set to one of the following:

         [TBADF]        The specified file descriptor does not refer to a
                        transport endpoint.

         [TOUTSTATE]    The function was issued in the wrong sequence.

         [TLOOK]        An asynchronous event has occurred on this transport
                        endpoint.

         [TSYSERR]      A system error has occurred during execution of this
                        function.

   DIAGNOSTICS
         t_unbind returns 0 on success and -1 on failure and t_errno is set to
         indicate the error.
