----------
This seems perfectly reasonable and useful.  Most of the previously
posted responses seem pretty obnoxious.  On the other hand, where
you should have put this is mod.std.c.  This is something that
belongs in the standard for the string library routines.

You might make a proposal for what value you'd like returned
if no null character is found before the given limit (-1 and size
are reasonable alternatives).
