t_unbind(3) — Subroutines
NAME
t_unbind − Disable a transport endpoint.
SYNOPSIS
#include <xti.h>
int t_unbind(
int fd );
LIBRARY
XTI Library (libxti.a)
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
t_unbind(): XNS4.0, XNS5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
The following table summarizes the relevance of input parameter data before and after t_bind() is called:
| Parameter | Before Call | After Call |
| fd | y | n |
Notes to Table:
yThis is a meaningful parameter.
nThis is not a meaningful parameter.
fdSpecifies a file descriptor returned by the t_open() function that identifies an active, previously bound local transport endpoint.
DESCRIPTION
The t_unbind() XTI service function is used in connection-oriented and connectionless modes to disable the transport endpoint, specified by the file descriptor that was previously bound by a t_bind() call. When t_bind() completes, no further data destined for this transport endpoint or events are accepted by the transport provider. An endpoint that has been disabled using t_unbind() can be enabled by a subsequent call to t_bind().
RETURN VALUES
Upon successful completion, a value of 0 (zero) is returned. Otherwise, a value of -1 is returned and t_errno is set to indicate the error.
ERRORS
If the t_unbind() function fails, t_errno is set to one of the following values:
[TBADF]
File descriptor fd is not a valid transport endpoint.
[TOUTSTATE]
This function was issued in the wrong sequence.
[TLOOK]
An asynchronous event occurred at the transport endpoint specified by the fd parameter.
[TSYSERR]
A system error occurred during execution of this function.
[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(t_errno).
VALID STATES
The t_bind() function can be called only in the T_IDLE transport provider state.
