debug.h

mpeg 2 source code for video compression

/*
	debug.h: 
		if DEBUG defined: debugging macro fprintf wrappers
		else: macros defined to do nothing
	That saves typing #ifdef DEBUG all the time and still preserves
	lean code without debugging.
	
	public domain (or LGPL / GPL, if you like that more;-)
	generated by debugdef.pl, what was
	trivially written by Thomas Orgis <[e-mail]>

/*
	I could do that with variadic macros available:
	#define sdebug(me, s) fprintf(stderr, "[" me "] " s "
")
	#define debug(me, s, ...) fprintf(stderr, "[" me "] " s "
", __VA_ARGS__)

	Variadic macros are a C99 feature...
	Now just predefining stuff non-variadic for up to 10 arguments.
	It's cumbersome to have them all with different names, though...
