// MEMTRACK.H
|
|
// Standard NetMeeting memory leak tracking.
|
|
//
|
|
// In retail:
|
|
// new/MemAlloc become LocalAlloc()
|
|
// MemReAlloc becomes LocalReAlloc()
|
|
// delete/MemFree become LocalFree()
|
|
//
|
|
// In debug:
|
|
// allocations are tracked, with module/file/line number
|
|
// leaked blocks are spewed when the module unloads
|
|
//
|
|
//
|
|
// USAGE:
|
|
// (1) Include this header and link to NMUTIL
|
|
// (2) If your component requires zero-initialized memory, define
|
|
// _MEM_ZEROINIT (for both debug and retail) in your SOURCES file
|
|
// (3) In your DllMain, on DLL_PROCESS_ATTACH call DBG_INIT_MEMORY_TRACKING,
|
|
// and on DLL_PROCESS_DETACH call DBG_CHECK_MEMORY_TRACKING
|
|
// (4) In DEBUG, you can make a call to DbgMemTrackDumpCurrent() to dump
|
|
// the currently allocated memory list from code.
