Sorry for not replying earlier, I've been so busy doing work I forgot to
Madhav M. was correct, I forgot to specify O_WRONLY. When I did that,
everything started to work. I was so busy trying to do the UDP/transfer
protocol stuff that I forgot the basics of file I/O. :(
Why do people keep saying "don't use int's, use FILEs"? As far as I know,
file descriptors (ints) are used internally by the OS, so a FILE is actually
a wrapper around a file descriptor.
Anyway, I am saving binary files, so I don't require the formatting of
fprintf, etc. I may as well use write instead of fwrite, and get to use one
less parameter that way too. But thanks for everyone's suggestions. Typical
the solution was something so easy/obvious :(
