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