||
| 32 | - These functions only work on C function names. Other languages may |
||
| 33 | have name mangling and intrinsic language support that varies from |
||
| 34 | compiler to compiler. |
||
| 35 | - Make sure you declare your function pointers with the same calling |
||
| 36 | convention as the actual library function. Your code will crash |
||
| 37 | mysteriously if you do not do this. |
||
| 38 | - Avoid namespace collisions. If you load a symbol from the library, |
||
| 39 | it is not defined whether or not it goes into the global symbol |
||
| 40 | namespace for the application. If it does and it conflicts with |
||
| 41 | symbols in your code or other shared libraries, you will not get |
||
| 42 | the results you expect. :) |
