Casting return to (void) was used to tell lint that you intended to ignore the return value, so it didn't warn you about it. Casting the third argument to (char *) was used as the most generic pointer type in the days before compilers supported C89 (void *) (except for a couple places it's used for byte-sized pointer math).
