 *  Some things to keep in mind:                                        

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

 *    have name mangling and intrinsic language support that varies from

 *    compiler to compiler.

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

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

 *    mysteriously if you do not do this.

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

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

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

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

 *    the results you expect. :)
