If you are compiling in C++, you almost HAVE to prototype your functions. C++
mangles the name so the linker can link by function name, not be paramaters
(which it won't reconize anyway). If it has no prototypes, it does not mangle.

If you get undefined references to names that are the literal names, make sure
you have a .h file defining them properly. Use the same .h file for the real
functions and the program and C++ will warn you of any mismatching functions.

If you are using C, forget what I just typed. :)
