C Language Style Guide

[Michael Madden]

Is there an accepted standard C language style guide.  I'm starting to develop
and test my applications on FreeBSD, and I want to ensure my code is readable
and maintainable.  I've been able to find specific project's guidelines like
the following, but I can find a general standard.  Does ANSI or POSIX dictate
anything about style or coding standards?

Thanks,
