/* 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. :)
