Networking Services Library Functionst_unbind(3NSL)


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 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 different 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
