There is nothing special about writing C for the arm, apart from a few
directives and switches. Details of these will be found at www.gnuarm.org

I assume that you are not particularly familiar with C programming, or
POSIX like environments. A good place to start would be to writing a
few simple C programs on Linux......this is easy to get hold of and
tutorials are abundant in many different languages.

Once you have grasped the basics of doing that, the transistion to,
say, an ARM microcontroller device, is just a matter of a few little
details.
