| 68 | This structure differs from the Win95 original, |
| 69 | but this should not matter since it is strictly internal to |
| 70 | the thunk handling routines in KRNL386 / KERNEL32. |
| 71 | |
| 72 | For reference, here is the Win95 layout: |
| 73 | |
| 74 | struct ThunkDataCommon common; /* 00 */ |
| 75 | DWORD flags1; /* 08 */ |
| 76 | SEGPTR apiDatabase; /* 0C */ |
| 77 | WORD exePtr; /* 10 */ |
| 78 | WORD segMBA; /* 12 */ |
| 79 | DWORD lenMBATotal; /* 14 */ |
| 80 | DWORD lenMBAUsed; /* 18 */ |
| 81 | DWORD flags2; /* 1C */ |
| 82 | char pszDll16[256]; /* 20 */ |
| 83 | char pszDll32[256]; /*120 */ |
| 84 | |
| 85 | We do it differently since all our thunk handling is done |
| 86 | by 32-bit code. Therefore we do not need do provide |
| 87 | easy access to this data, especially the process target |
| 88 | table database, for 16-bit code. |
