NAME
     t_rcvrel - acknowledge receipt of an orderly release indica-
          tion

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 end-
     point 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
     t_sndrel(3N) has not been issued by the user.

     This function is an optional service of the transport pro-
     vider, 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.

     [TNOREL]            No orderly release indication currently
                         exists on the specified transport end-
                         point.

     [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 exe-
                         cution of this function.

DIAGNOSTICS
     trcvrel returns 0 on success and -1 on failure t_errno is
     set to indicate the error.
