NAME
t_unbind - disable a transport endpoint

SYNOPSIS
#include <xti.h>

int t_unbind(int fd);

DESCRIPTION
The This routine is part of the XTI interfaces which evolved from the
TLI interfaces. XTI represents the future evolution of these inter‐
faces. However, TLI interfaces are supported for compatibility. When
using a TLI routine that has the same name as an XTI routine, the
tiuser.h header file must be used. Refer to the TLI COMPATIBILITY
section for a description of differences between the two interfaces.

t_unbind() function disables the transport endpoint specified by fd
which was previously bound by t_bind(3NSL). On completion of this call,
no further data or events destined for this transport endpoint will be
accepted by the transport provider. An endpoint which is disabled by
using t_unbind() can be enabled by a subsequent call to t_bind(3NSL).

RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a
value of -1 is returned and t_errno is set to indicate an error.

VALID STATES
T_IDLE.

ERRORS
On failure, t_errno is set to one of the following:

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

TLOOK An asynchronous event has occurred on this transport
endpoint.

TOUTSTATE The communications endpoint referenced by fd is not in
one of the states in which a call to this function is
valid.

TPROTO This error indicates that a communication problem has
been detected between XTI and the transport provider
for which there is no other suitable XTI error
(t_errno).

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

TLI COMPATIBILITY
The XTI and TLI interface definitions have common names but use differ‐
ent header files. This, and other semantic differences between the two
interfaces are described in the subsections below.

Interface Header
The XTI interfaces use the header file, xti.h . TLI interfaces should
not use this header. They should use the header:

#include <tiuser.h>

Error Description Values
The t_errno value that can be set by the XTI interface and cannot be
set by the TLI interface is:

TPROTO
