kernel32.h

Abstract:
|
||
|
|
|
||
|
|
The heap manager is identical (exactly) to the Win9x heap manager. The code
|
||
|
|
is the same and the corresponding conversion code and defines are in
|
||
|
|
support.c and kernel32.h The exact win9x sources are in heap.c and lmem.c.
|
||
|
|
All the heap functions come in heap.c and the local/global functions come
|
||
|
|
in lmem.c.
|
||
|
|
|
||
|
|
The SHIM code comes in EmulateHeap.cpp. This hooks the heap calls and calls
|
||
|
|
the Win9x code to emulate the Win9x heap. After the heap management by the
|
||
|
|
Win9x heap, the underneath calls to the Virtual memory functions are handled
|
||
|
|
in support.c. The only difference comes in the way Win9x handles 'SHARED'
|
||
|
|
and "PRIVATE' heaps.Win9x creates the process default heap as a SHARED heap
|
||
|
|
and uses it in kernel mode too. We also create it as a SHARED heap but do
|
||
|
|
not share it with the kernel. Win9x links all the PRIVATE heaps for the
|
||
|
|
process in the PDB data structure. We fake this structure with only the
|
||
|
|
required elements and allow the Win9x code to handle this structure.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
None.
