+/*++
+/* NAME
+/*	timed_ipc 3
+/* SUMMARY
+/*	enforce IPC timeout on stream
+/* SYNOPSIS
+/*	#include <time_ipc.h>
+/*
+/*	void	timed_ipc_setup(stream)
+/*	VSTREAM	*stream;
+/* DESCRIPTION
+/*	timed_ipc() enforces on the specified stream the timeout as
+/*	specified via the \fIipc_timeout\fR configuration parameter:
+/*	a read or write operation fails if it does not succeed within
+/*	\fIipc_timeout\fR seconds. This deadline exists as a safety
+/*	measure for communication between mail subsystem programs,
+/*	and should never be exceeded.
+/* DIAGNOSTICS
+/*	Panic: sanity check failed. Fatal error: deadline exceeded.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
