||
| 25 | * System dependent library loading routines |
||
| 26 | * |
||
| 27 | * Some things to keep in mind: |
||
| 28 | * \li These functions only work on C function names. Other languages may |
||
| 29 | * have name mangling and intrinsic language support that varies from |
||
| 30 | * compiler to compiler. |
||
| 31 | * \li Make sure you declare your function pointers with the same calling |
||
| 32 | * convention as the actual library function. Your code will crash |
||
| 33 | * mysteriously if you do not do this. |
||
| 34 | * \li Avoid namespace collisions. If you load a symbol from the library, |
||
| 35 | * it is not defined whether or not it goes into the global symbol |
||
| 36 | * namespace for the application. If it does and it conflicts with |
||
| 37 | * symbols in your code or other shared libraries, you will not get |
||
| 38 | * the results you expect. :) |
