t_rcvrel(3N)                     DG/UX 5.4.2                    t_rcvrel(3N)


NAME
       trcvrel - acknowledge receipt of an orderly release indication

SYNOPSIS
       #include <tiuser.h>

       trcvrel (int fd);

DESCRIPTION
       This function is used to acknowledge receipt of an orderly release
       indication.  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 tsndrel 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
       TCOTSORD on topen or tgetinfo.

       On failure, terrno 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 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.
