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