    27    - These functions only work on C function names.  Other languages may

    28      have name mangling and intrinsic language support that varies from

    29      compiler to compiler.

    30    - Make sure you declare your function pointers with the same calling

    31      convention as the actual library function.  Your code will crash

    32      mysteriously if you do not do this.

    33    - Avoid namespace collisions.  If you load a symbol from the library,

    34      it is not defined whether or not it goes into the global symbol

    35      namespace for the application.  If it does and it conflicts with

    36      symbols in your code or other shared libraries, you will not get

    37      the results you expect. :)
