Re^2: Redirecting XS stdout

++ You know what, that's just the key I needed!

I'm trying to wrap some C with as little modification as possible (staying current with the upstream). I didn't want to replace any IO calls directly, but after *seeing* your PerlIO call it dawned on me to simply override the stdio calls with PerlIO.

#define fprintf(fh,...) PerlIO_printf(fh,__VA_ARGS__);
#define stdout PerlIO_stdout()
#define stderr PerlIO_stderr()

Thanks!

Exactly. You'd think something like this already exists. Maybe it does. (Google code search?)	[reply]

Maybe it does fakesdio.h It is part of the base perl source code. See also perlsdio.h.	[reply]

I think I've figured out why I didn't stumble on this method before.. After redefining the macros, I discovered the code I'm wrapping is taking the "return early, return often" concept to the extreme by way of exits. Oh well, back to the drawing board! Thanks again :)	[reply]
