|
* System dependent library loading routines |
|
* |
|
* Some things to keep in mind: |
|
* \li These functions only work on C function names. Other languages may |
|
* have name mangling and intrinsic language support that varies from |
|
* compiler to compiler. |
|
* \li 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. |
|
* \li 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. :) |
