This one is taxing me, what is the correct type returned by the built in
sizeof() operator ?
int ?
unsigned int ?
size_t ?
ssize_t ?
Where does size_t and ssize_t originate from ? ANSI/stdio ?

This is a general C question, not a gcc question. As such, it should
probably go to a mailing list about C, not to a mailing list
specifically about gcc. Thanks.
The answer is that sizeof returns a value of type size_t.

I believe size_t was introduced in the ISO C90 standard. I believe
that ssize_t was introduced in the second edition of the POSIX 1003.1
standard (1003.1-1996).
