/*
* FILE
*
* vargs.h include file for environments without varargs.h
*
* SCCS
*
* @(#)vargs.h 1.2 5/8/88
*
* SYNOPSIS
*
* #include "vargs.h"
*
* DESCRIPTION
*
* This file implements a varargs macro set for use in those
* environments where there is no system supplied varargs. This
* generally works because systems which don't supply a varargs
* package are precisely those which don't strictly need a varargs
* package. Using this one then allows us to minimize source
* code changes. So in some sense, this is a "portable" varargs
* since it is only used for convenience, when it is not strictly
* needed.
*
*/
/*
* These macros allow us to rebuild an argument list on the stack
* given only a va_list. We can use these to fake a function like
* vfprintf, which gets a fixed number of arguments, the last of
* which is a va_list, by rebuilding a stack and calling the variable
* argument form fprintf. Of course this only works when vfprintf
* is not available in the host environment, and thus is not available
* for fprintf to call (which would give us an infinite loop).
*
* Note that ARGS_TYPE is a long, which lets us get several bytes
* at a time while also preventing lots of "possible pointer alignment
* problem" messages from lint. The messages are valid, because this
* IS nonportable, but then we should only be using it in very
* nonrestrictive environments, and using the real varargs where it
* really counts.

* For our case, we first increment the va_list arg by the
* size of the type being recovered, cast the result to
* a pointer of the appropriate type, and then dereference
* that pointer as an array to get the previous arg (which
