// Description: |
|
14 |
// Purpose: The DProcessTracker object tracks which processes are being |
|
15 |
// debugged. The DProcessTracker class uses a DTargetProcess object for |
|
16 |
// each process being debugged. |
|
17 |
// Note: Although TheDProcessTracker object is a global, it will be unique |
|
18 |
// as only the Debug Security Server can load and use rm_debug.ldd. |
|
