Name
t_sndrel - initiate an orderly release
Syntax
#include <tiuser.h>
int t_sndrel(fd)
int fd;
Description
This function is used to initiate an orderly release of a
transport connection and indicates to the transport provider
that the transport user has no more data to send. fd
identifies the local transport endpoint where the connection
exists. After issuing t_sndrel, the user may not send any
more data over the connection. However, a user may continue
to receive data if an orderly release indication has been
received.
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.
On failure, t_errno may be set to one of the following:
[TBADF] The specified file descriptor does not
refer to a transport endpoint.
[TFLOW] O_NDELAY was set, but the flow control
mechanism prevented the transport
provider from accepting the function at
this time.
[TNOTSUPPORT] This function is not supported by the
underlying transport provider.
[TSYSERR] A system error has occurred during
execution of this function.
