NAME

       t_sndrel() - initiate an orderly release

SYNOPSIS

DESCRIPTION

       The  function  is  used in connection-oriented mode to initiate an orderly release at a transport endpoint specified by fd, which is a file
       descriptor previously returned by the 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, the transport user may continue to receive data over
       the connection until an orderly release indication is received.	This function is an optional service of the transport provider and is only
       supported if the transport provider returned service type on or

       [TFLOW]		   Asynchronous mode is indicated because was set, but the transport provider cannot accept a release because of flow-con-
			   trol 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.

       [TSYSERR]	   A system error has occurred during execution of this function.

       [TPROTO] 	   (XTI only) This error indicates that a communication problem has been detected between XTI and the  transport  provider
			   for which there is no other suitable XTI (
