fgetc and EOF

True...

It's probably so you can do this:

Code:

if ((i = fgetc(stdin)) < 0) /* error */

Why I didn't think of this before, I don't know...

I reasoned that since EOF is negative and the normal return values of fgetc() are non-negative in a range almost definitely smaller than int, there can be no conflict between them. I did not state that to avoid such a conflict, EOF was defined to be negative (though this may indeed have been an intention of whoever designed this part of the standard library).

Oh ok, I see now.

Sorry for the trouble.
