The This routine is part of the XTI interfaces which evolved from the
TLI interfaces. XTI represents the future evolution of these
interfaces. 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).
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.
T_IDLE.
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.
The XTI and TLI interface definitions have common names but use
different header files. This, and other semantic differences between
the two interfaces are described in the subsections below.
The XTI interfaces use the header file, xti.h . TLI interfaces should
not use this header. They should use the header:
#include <tiuser.h>
The t_errno value that can be set by the XTI interface and cannot be
set by the TLI interface is:

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
interfaces. 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

TLI COMPATIBILITY
The XTI and TLI interface definitions have common names but use

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
