NAME

t_sndrel - Initiates an endpoint connect orderly release  

LIBRARY

XTI Library (libxti.a)  

SYNOPSIS

#include <xti.h>

int t_sndrel(
    int fd) ;  

STANDARDS

Interfaces documented on this reference page conform to industry standards as follows:

t_sndrel:       XPG4-UNIX

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_sndrel() is called:

ParameterBefore CallAfter Call

fdyn
Notes to Table:

y    This is a meaningful parameter.
n    This is not a meaningful parameter.
fd
Specifies a file descriptor returned by the t_open() function that identifies a local transport endpoint where an orderly release is wanted.
 

VALID STATES

The t_sndrel() function can be called only in the T_DATAXFER and T_INREL transport provider states.  

DESCRIPTION

The t_sndrel() XTI function is used in connection-oriented mode to initiate an orderly release at a transport endpoint specified by a file descriptor previously returned by the t_open() function.

After this orderly release is indicated, the transport user should not try to send more data through that transport endpoint; an attempt to send more data to a released transport endpoint may block continuously. However, a transport user may continue to receive data over the connection until an orderly release indication is received.

The t_sndrel() function should not be used unless the servtype type-of-service returned by the t_open() or t_getinfo() function is T_COTS_ORD (supports connection-mode service with the optional orderly release facility).  

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 an error.  

ERRORS

If the t_sndrel(|) function fails, t_errno may be set to one of the following values:

[TBADF]
File descriptor fd does not refer to a valid transport endpoint.
[TFLOW]
Asynchronous mode is indicated because O_NONBLOCK was set, but the transport provider cannot accept a release because of flow-control restrictions.
[TLOOK]
An asynchronous event has occurred on this transport endpoint and requires immediate attention.
[TNOTSUPPORT]
This function is not supported by the underlying transport provider.
[TOUTSTATE]
The t_sndrel() function was issued in the wrong sequence 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).
