To be fair, returning structures was poorly supported once. Of course that was in about 1980, but it explains some properties of the standard C and POSIX library (e.g. why stat() does not return a 'struct stat').

I'd say another reason is that it's much easier to check for errors if your function returns some integer and passes the real result via a pointer.

Well, if there's only one error, it's easier to use the function if you just return the pointer or NULL.

Or to emulate old-school styles return NULL and set the global errno ;-)
