Yes, it is. Unfortunately, it's also wrong. If you have a pointer to char but need to treat the data it points to as unsigned char, you have to cast the pointer and dereference it to get the correct value on ones complement systems -- dereferencing and then casting doesn't work because -0 gets converted to +0. -Larry Jones Somebody's always running my life.
