| History |
| |
| 0.1 + First realised, kernel load dll.obj at runtime as starting point berfore app startup |
| dll.obj process app import table, but not depended librarys, after that app gots control in his starting point |
| |
| 0.2 + Introduced new KX header as extension for current format (see decription below) |
| + Add KX header processing |
| + Improved import table test logic, no reason to kill app for import absence - skip import processing (tnx ProMiNick) |
| |

| Purpose |
| |
| Automatically libraries loads and linking imports. |
| |
| --- |
| Limitations |
| |
| |
| 1) No error messages are issued if the library or symbol in the library is not found or somthing went wrong |
| |
| |
| 2) There is no autoloading of dependent libraries (the library format needs to be improved, see intorduction of KX header extension bellow) |
| |
| --- |
| How to use |
| |
| - in app: |
| 1) In the version field of a header, (after MENUET0x) you must specify the number 2 |
| 2) After existing header add KX header extension as descriprion bellow |
| 3) Specify imported libraries. Currentry format of import table same as in case of using dll.Load |
| 4) Add code, without connecting dll.inc and, accordingly, without calling dll.Load. The heap initialization function (f. 68.11) does not need to be called either. |
| |
| 5) Compile the app and run. If everything is done correctly, then on startup the debug board will display the message "App header version 2" |
| If the DLL.OBJ library is missing, a message will be displayed, incl. via @NOTIFY. If you get a page error make sure you have completed steps 2 and 3 |
| |
| - in lib (obj): |
| Not supported yet, will be realized later. |
| 1) Field optHeader of COFF header need set in 8+n*4, where n is count of fields after KX header |
| 2) After COFF header add KX header extension (in general same as in case for app) |

| Descriprion of KX header extension (alpha). |
| |
| TBD is meaning that this feature to be determined leter, and not supported yet. |
| By default all offsets and sizes given in bytes, for Flags field offsets and size given in bits. |
| Offset 4.x meaning offset 4 bit x |
| |
| Fields between offset 8 and at end of KX header may be added later. |
