- Revision 1.4 2004/02/20 17:19:10 savage
- Added Calling convention to Win32 functions just in case.
-
- Revision 1.3 2004/02/14 22:36:29 savage
- Fixed inconsistencies of using LoadLibrary and LoadModule.
- Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
-
- Revision 1.2 2004/02/14 00:23:39 savage
- As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
-
- Revision 1.1 2004/02/14 00:04:50 savage
- dllfuncs conflicts with FreePascal so it has been renamed back to the moduleloader.pas
-
- Revision 1.1 2004/02/05 00:08:19 savage
- Module 1.0 release
