Tables of names and headers for

Both tables are sorted in ASCII order. They have been compiled from the Standards documents with great care and are believed to be highly accurate. If you find an error or omission in these tables, I'd be more than thankful to hear about it - please let me know so I can fix it. If you are concerned about name clashes in your c code (honest: did you know that you can't write a non-static function named Cleared() without invoking undefined behavior?) you'll definitely not regret following this link.

ISO C Names and corresponding headers:

Note: the math functions in math.h come in three flavors. The C89 Standard requires only functions taking and returning double arguments. C89 Section 7.13.4 on "Future library directions" states for math.h that "The names of all existing functions declared in the <math.h> header, suffixed with f or l, are reserved respectively for corresponding functions with float and long double arguments and return values."
