     NAME
          t_unbind - disable a transport endpoint

     SYNOPSIS
          #include <tiuser.h>

          int tunbind(fd)
          int fd;

     DESCRIPTION
          The tunbind function disables the transport endpoint
          specified by fd which was previously bound by tbind (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.

     SEE ALSO
          t_bind(3N).

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