NAME
trcvrel - acknowledge receipt of an orderly release indication
SYNOPSIS
#include <sys/tiuser.h>
int trcvrel(int fd);
DESCRIPTION
This function is used to acknowledge receipt of an orderly release
indication. fd identifies the local transport endpoint where the con-
nection exists. After receipt of this indication, the user should not
attempt to receive more data because such an attempt will block for-
ever. However, the user may continue to send data over the connection
if tsndrel 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
TCOTSORD on topen or tgetinfo.
On failure, terrno 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 endpoint.
TLOOK An asynchronous event has occurred on this transport
endpoint and requires immediate attention.
