* Heap debugging functions (interface). |
|
|
3 |
* |
|
|
4 |
* Based on memdebug.h from curl (see below), with the following modifications: |
|
|
5 |
* |
|
|
6 |
* - renamed functions from curl_ to memdebug_ |
|
|
7 |
* - added memdebug_strndup |
|
|
8 |
* - added guard bytes before and after each block to help detect overflows |
|
|
9 |
* - if a guard byte is corrupted during free, dumps the DA to file |
