  25  *  System dependent library loading routines
  26  *
  27  *  Some things to keep in mind:
  28  *  \li These functions only work on C function names.  Other languages may
  29  *      have name mangling and intrinsic language support that varies from
  30  *      compiler to compiler.
  31  *  \li Make sure you declare your function pointers with the same calling
  32  *      convention as the actual library function.  Your code will crash
  33  *      mysteriously if you do not do this.
  34  *  \li Avoid namespace collisions.  If you load a symbol from the library,
  35  *      it is not defined whether or not it goes into the global symbol
  36  *      namespace for the application.  If it does and it conflicts with
  37  *      symbols in your code or other shared libraries, you will not get
  38  *      the results you expect. :)
