Hi,
I am new to C so please bear with my stupid questions. I am
trying to open a file to write, but the code complains that it is
unable to do so. How do I get C to print the reason it is failing?
Something like the $! function in perl. Thanks a lot for all your
help.

perror() may be what you're looking for.
I don't believe fopen is required to set errno when it fails, but on
every implementation I've encountered it does. (That may be influenced
by the fact that most of the implementations I've used are unixy, and I
think POSIX *does* require the underlying system calls to set errno.)

this seemed the perfect excuse to find out - and it appears to have worked.
