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. :)
