t_rcvrel -- acknowledge receipt of an orderly release indication

Synopsis

cc [options] file -lnsl

#include <xti.h>

int t_rcvrel(int fd);

Description

This function is a TLI/XTI connection release routine used to acknowledge receipt of an orderly release indication. In t_rcvrel, fd identifies the local transport endpoint where the connection exists. After receipt of this indication, the user should not attempt to receive more data because such an attempt will block forever. However, the user may continue to send data over the connection if t_sndrel has not been issued by the user.

This function is an optional service of the transport provider, and is only supported if the transport provider returned service type T_COTS_ORD on t_open or t_getinfo.

Parameters

fd: the file descriptor for the transport endpoint where the connect indication is received.

State transitions

T_DATAXFER on entry and T_INREL on exit; or T_OUTREL on entry and T_IDLE on exit.

Return values

t_rcvrel returns 0 on success and -1 on failure t_errno is set to indicate the error.

Errors

On failure, t_errno may be set to one of the following:

TBADF: The specified file descriptor does not refer to a transport endpoint.
TNOREL: No orderly release indication currently exists on the specified transport endpoint.
TLOOK: An asynchronous event has occurred on the transport endpoint specified by fd and requires immediate attention.
TNOTSUPPORT: This function is not supported by the underlying transport provider.
TSYSERR: A system error has occurred during execution of this function.
TOUTSTATE: The function was issued in the wrong sequence on the transport endpoint referenced by fd.
TPROTO: A communication problem has been detected with the transport provider and there is no other value of t_errno to describe the error condition.
