Oh, ok. I was more thinking along the lines of using symbolic values, kind of like this: #define CTTY_UNINITIALIZED -1 #define CTTY_RELEASED -2 #define CTTY_IS_FREE(_c) ((_c) < 0) I'm not sure the names make sense, but you see what I mean. The comments could precede the definitions in the header file then. Corinna
