T_SNDREL(3N)                         SysV                         T_SNDREL(3N)



NAME
     t_sndrel - initiate an orderly release

SYNOPSIS
     #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.

DIAGNOSTICS
     t_sndrel returns 0 on success and -1 on failure and 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.

     [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.
