Hi Paul,
Right, but I was thinking we'd be doing:
isdigit((unsigned char) c);
Which, AFAIK, is correct.
Some people advocated (and I thought that's what Lyndon was talking
about):
isdigit((int)(unsigned char) c);
NetBSD's man page suggested the (int) because of a compiler bug, I think
it shouldn't be done... That could be a very old bug.
doesn't ansi c require the isdigit implementation to do that?
That's my understanding.
Cheers, Ralph.
