Damn. Need to be more careful with stack stuff.

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. :) | |
