T_UNBIND(3N)                         SysV                         T_UNBIND(3N)



NAME
     t_unbind - disable a transport endpoint

SYNOPSIS
     #include <tiuser.h>

     int t_unbind(fd)
     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.

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

ERRORS
     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.
