Syntax
#include <xti.h>
int t_rcvrel(fd)
int fd;
Arguments
fdIdentifies the local transport endpoint.
Description
This function is used to acknowledge receipt of an orderly release indication. After receipt of this indication, the user cannot attempt to receive more data, because such an attempt will block forever. However, the user can continue to send data over the connection if t_sndrel() 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 T_COTS_ORD on t_open() or t_getinfo().
