The strnstr() function takes a length, and can thus be safely used on
buffers which contain no NUL byte.
As far as I can tell it only takes one length, and that's for the
string to be searched, so he will have to NULL-terminate the search
string (which is what WT was talking about as far as I can tell).
Well that would be the case if strnstr() were actually useful for him,
which I guess it isn't.
On Tiger and earlier, strnstr() had a bug where it could read one byte
past the length specified, which could cause a crash in certain
circumstances. Had a grand old time tracking that one down, I did. It
was eventually fixed in a security update, and I believe it was fixed
in Leopard from the start.
Funky stuff!
