    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. :)
