PaUtil_SetLogPrintFunction can be user called to replace the provided DefaultLogPrint function, which writes to stderr. One can NOT pass var_args across compiler/dll boundaries as it is not "byte code/abi portable". So the technique used here is to allocate a local a static array, write in it, then callback the user with a pointer to its start.

PA_DEBUG() provides a simple debug message printing facility. The macro passes it's argument to a printf-like function called PaUtil_DebugPrint() which prints to stderr and always flushes the stream after printing. Because preprocessor macros cannot directly accept variable length argument lists, calls to the macro must include an additional set of parenthesis, eg: PA_DEBUG(("errorno: %d", 1001 ));
