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  con‐
       nection 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

RETURN VALUE
       Upon  successful	 completion,  a	 value of 0 is returned.  Otherwise, a
       value of −1 is returned and is set to indicate the error.

ERRORS
       On failure, is set to one of the following:

       [TBADF]		   The specified identifier does not refer to a trans‐
			   port endpoint.

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

       [TLOOK]		   An  asynchronous  event has occurred on this trans‐
			   port 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  communica‐
			   tion	 problem has been detected between XTI and the
			   transport provider for  which  there	 is  no	 other
			   suitable XTI (
