Thread: memory functions not in Win98

I'm trying to learn about heap allocation, walking, deallocation,
etc. but every function/struct I get from MSDN says it's not
supported by Win98 only WinNT.

ie:

PROCESS_HEAP_ENTRY
HeapWalk()

Windows NT: Requires version 3.5 or later.
Windows: Unsupported

_heapwalk()
Note Beginning with Visual C++ Version 4.0, the underlying heap structure was moved to the C run-time libraries to support the new debugging features. As a result, the only Win32 platform that is supported by _heapwalk is Windows NT. When it is called by any other Win32 platform, _heapwalk returns _HEAPEND and sets errno to ENOSYS.

But there's no mention/link/etc. to whatever replaced these.

For clarification I understand new and delete. What I'm trying to
learn now is how to walk the heap and get the info (for tracking
leaks, etc.)
