66 This structure differs from the Win95 original,
67 but this should not matter since it is strictly internal to
68 the thunk handling routines in KRNL386 / KERNEL32.
69
70 For reference, here is the Win95 layout:
71
72 struct ThunkDataCommon common; /* 00 */
73 DWORD flags1; /* 08 */
74 SEGPTR apiDatabase; /* 0C */
75 WORD exePtr; /* 10 */
76 WORD segMBA; /* 12 */
77 DWORD lenMBATotal; /* 14 */
78 DWORD lenMBAUsed; /* 18 */
79 DWORD flags2; /* 1C */
80 char pszDll16[256]; /* 20 */
81 char pszDll32[256]; /*120 */
82
83 We do it differently since all our thunk handling is done
84 by 32-bit code. Therefore we do not need do provide
85 easy access to this data, especially the process target
86 table database, for 16-bit code.
