This structure differs from the Win95 original,
|
|
but this should not matter since it is strictly internal to
|
|
the thunk handling routines in KRNL386 / KERNEL32.
|
|
|
|
For reference, here is the Win95 layout:
|
|
|
|
struct ThunkDataCommon common; /* 00 */
|
|
DWORD flags1; /* 08 */
|
|
SEGPTR apiDatabase; /* 0C */
|
|
WORD exePtr; /* 10 */
|
|
WORD segMBA; /* 12 */
|
|
DWORD lenMBATotal; /* 14 */
|
|
DWORD lenMBAUsed; /* 18 */
|
|
DWORD flags2; /* 1C */
|
|
char pszDll16[256]; /* 20 */
|
|
char pszDll32[256]; /*120 */
|
|
|
|
We do it differently since all our thunk handling is done
|
|
by 32-bit code. Therefore we do not need do provide
|
|
easy access to this data, especially the process target
|
|
table database, for 16-bit code.
