    28  *  Some things to keep in mind:

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

    30  *    have name mangling and intrinsic language support that varies from

    31  *    compiler to compiler.

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

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

    34  *    mysteriously if you do not do this.

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

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

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

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

    39  *    the results you expect. :)
