+/*++
+/* NAME
+/*	msg_vstream 3
+/* SUMMARY
+/*	report diagnostics to VSTREAM
+/* SYNOPSIS
+/*	#include <msg_vstream.h>
+/*
+/*	void	msg_vstream_init(progname, stream)
+/*	const char *progname;
+/*	VSTREAM	*stream;
+/* DESCRIPTION
+/*	This module implements support to report msg(3) diagnostics
+/*	to a VSTREAM.
+/*
+/*	msg_vstream_init() sets the program name that appears in each output
+/*	record, and directs diagnostics (see msg(3)) to the specified
+/*	VSTREAM. The \fIprogname\fR argument is not copied.
+/* SEE ALSO
+/*	msg(3)
+/* BUGS
+/*	No guarantee that long records are written atomically.
+/*	Only the last msg_vstream_init() call takes effect.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
