Matt,

As you already stated yourself, you can use a global variable for this.

If you want thread-safety (which I wanted), however, you'll have to resort
to something more obscure: in my case, I used an extension of gcc called
'nested functions' (defining functions in functions). These functions are
scoped within their 'parent', and can access all of its variables and
arguments.

I know it's not portable (in fact, I stumbled upon an internal gcc bug
implementing it), but I use gcc as the only compiler for my project, and
the code is surrounded with a big #ifdef __GNUC__ :)
