t_rcvrel - acknowledge receipt of an orderly release indication
t_rcvel() acknowledges receipt of an orderly release indication. fd
identifies the local transport endpoint where the connection exists.
After receipt of this indication, the user may 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.
t_rcvrel() 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(3N) or t_getinfo(3N).
0 on success.
-1 on failure and sets t_errno to indicate the error.
