NAME

       t_rcvrel - Acknowledges receipt of an orderly release indication

LIBRARY

       XTI Library (libxti.a)

SYNOPSIS

       #include <xti.h>

       int t_rcvrel(
	 int fd) ;

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       t_rcvrel():  XNS4.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       The following table summarizes the relevance of input parameter data before and after t_rcvrel() is called:

							  Parameter   Before Call   After Call
							  -------------------------------------
							     fd 	   y		n
       Notes to Table:
	      y    This is a meaningful parameter.
	      n    This is not a meaningful parameter.

       fd     Specifies a file descriptor returned by the t_open() function that identifies a local transport endpoint that has been released.

VALID STATES

       The t_rcvrel() function can be called only in the T_DATAXFER and T_OUTREL transport provider states.

DESCRIPTION

       The t_rcvrel() XTI function is used in connection-oriented mode to acknowledge receipt of an orderly release indication at a transport end-
       point. The released endpoint is specified by a file descriptor previously returned by the t_open() function.

       After receipt of this orderly release indication, at the transport endpoint specified by the file descriptor, a transport user  should  not
       try  to	receive  additional  data from that transport endpoint. Any attempt to receive more data from a released transport endpoint blocks
       continuously.  However, a transport user may continue to send data across the connection until a release is sent by a  transport  user  who
       invokes a t_sndrel() function call.

       The  t_rcvrel()	function  should  not  be  used  unless  the servtype type-of-service returned by the t_open() or t_getinfo() functions is
       T_COTS_ORD (supports connection-mode service with the optional orderly release facility).

RETURN VALUE

       Upon successful completion, a value of 0 (zero) is returned. Otherwise, a value of -1 is returned and t_errno is set to indicate the error.

ERRORS

       If the t_rcvrel() function fails, t_errno may be set to one of the following values:

       [TBADF]	 File descriptor fd does not refer to a valid transport endpoint.

       [TNOREL]  No orderly release indication currently exists at the transport endpoint specified by the fd parameter.

       [TLOOK]	 An asynchronous event has occurred on the transport endpoint specified by the fd parameter and requires immediate attention.

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

       [TOUTSTATE]
		 The t_rcvrel() function was issued in the wrong sequence at the transport endpoint referenced by the fd parameter.

       [TNOTSUPPORT]
		 This function is not supported by the underlying transport provider.

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