                     32:    - These functions only work on C function names.  Other languages may
                     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
                     41:      symbols in your code or other shared libraries, you will not get
                     42:      the results you expect. :)
