/* 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.
