AFAIK who parameters are passed to the called function depends on the architecture (stack or some registers + stack). I vaguely remember some MIPS ASM programming exercises in first year of university... But if gcc has a in built function, that should do on all architectures, though. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
