I also wanted to know if it mattered. You should normally pass the type 'char'.

By definition sizeof(char) == 1. You can find the minimum and maximum valuesof char by #include <limits.h> and looking at CHAR_MIN and CHAR_MAX. > I tried using unsigned chars and char and then compiling with the option > -unsigned-char (I think it's called) but I'm still getting warnings like: > > -wsign-compare > XXXXXXX function expected `char' but argument is type `unsigned char' That is as expected. By the way, these questions are more related to C in general than to GCC in particular. Ian
