TSNDREL(3N)               DG/UX 4.30                TSNDREL(3N)



     NAME
          t_sndrel - initiate an orderly release

     SYNOPSIS
          #include <tiuser.h>

          int tsndrel(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 tsndrel, 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 topen or tgetinfo.

          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.

     SEE ALSO
          t_open(3N), t_rcvrel(3N).

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