Hmm... ever tried Kernighan & Ritchie, The C Programming Language,
2nd edition?

_After_ mastering that, you can try Advanced Programming in the Unix
Environment, W. Richard Stevens.

int main (void) is the correct way.

Not safe. Try 
getnstr (buff, sizeof buff);

You didn't mention the error you got. If it is a linker error, you have
to add -lcurses to the compilation command line.

I don't know how the dos getch() function works, so I cannot comment
on that.

Stevens above is, in my opinion, the most authoritative book that you
can find anywhere on Unix programming.

If you are talking about ANSI C, try the newsgroup comp.lang.c. Some
great C experts post there. For Linux programming, you are at the
right place - also, you can try comp.unix.programmer for generic Unix
programming issues. Both newsgroups are accessible from www.my-deja.com.
