- Revision 1.17 2005/01/03 18:40:59 savage
- Updated Version number to reflect latest one
-
- Revision 1.16 2005/01/01 02:02:06 savage
- Updated to v1.2.8
-
- Revision 1.15 2004/12/24 18:57:11 savage
- forgot to apply Michalis Kamburelis' patch to the implementation section. now fixed
-
- Revision 1.14 2004/12/23 23:42:18 savage
- Applied Patches supplied by Michalis Kamburelis ( THANKS! ), for greater FreePascal compatability.
-
- Revision 1.13 2004/09/30 22:31:59 savage
- Updated with slightly different header comments
-
- Revision 1.12 2004/09/12 21:52:58 savage
- Slight changes to fix some issues with the sdl classes.
-
- Revision 1.11 2004/08/14 22:54:30 savage
- Updated so that Library name defines are correctly defined for MacOS X.
-
- Revision 1.10 2004/07/20 23:57:33 savage
- Thanks to Paul Toth for spotting an error in the SDL Audio Convertion structures.
- In TSDL_AudioCVT the filters variable should point to and array of pointers and not what I had there previously.
-
- Revision 1.9 2004/07/03 22:07:22 savage
- Added Bitwise Manipulation Functions for TSDL_VideoInfo struct.
-
- Revision 1.8 2004/05/10 14:10:03 savage
- Initial MacOS X support. Fixed defines for MACOS ( Classic ) and DARWIN ( MacOS X ).
-
- Revision 1.7 2004/04/13 09:32:08 savage
- Changed Shared object names back to just the .so extension to avoid conflicts on various Linux/Unix distros. Therefore developers will need to create Symbolic links to the actual Share Objects if necessary.
-
- Revision 1.6 2004/04/01 20:53:23 savage
- Changed Linux Shared Object names so they reflect the Symbolic Links that are created when installing the RPMs from the SDL site.
-
- Revision 1.5 2004/02/22 15:32:10 savage
- SDL_GetEnv Fix so it also works on FPC/Linux. Thanks to Rodrigo for pointing this out.
-
- Revision 1.4 2004/02/21 23:24:29 savage
- SDL_GetEnv Fix so that it is not define twice for FPC. Thanks to Rene Hugentobler for pointing out this bug,
-
- Revision 1.3 2004/02/18 22:35:51 savage
- Brought sdl.pas up to 1.2.7 compatability
- Thus...
- Added SDL_GL_STEREO,
- SDL_GL_MULTISAMPLEBUFFERS,
- SDL_GL_MULTISAMPLESAMPLES
-
- Add DLL/Shared object functions
- function SDL_LoadObject( const sofile : PChar ) : Pointer;
-
- function SDL_LoadFunction( handle : Pointer; const name : PChar ) : Pointer;
-
- procedure SDL_UnloadObject( handle : Pointer );
-
- Added function to create RWops from const memory: SDL_RWFromConstMem()
- function SDL_RWFromConstMem(const mem: Pointer; size: Integer) : PSDL_RWops;
-
- Ported SDL_cpuinfo.h so Now you can test for Specific CPU types.
-
- Revision 1.2 2004/02/17 21:37:12 savage
- Tidying up of units
-
- Revision 1.1 2004/02/05 00:08:20 savage
- Module 1.0 release
