        !            33:      have name mangling and intrinsic language support that varies from
        !            34:      compiler to compiler.
        !            35:    - Make sure you declare your function pointers with the same calling
        !            36:      convention as the actual library function.  Your code will crash
        !            37:      mysteriously if you do not do this.
        !            38:    - Avoid namespace collisions.  If you load a symbol from the library,
        !            39:      it is not defined whether or not it goes into the global symbol
        !            40:      namespace for the application.  If it does and it conflicts with

        !            42:      the results you expect. :)
