Inside Macintosh: OpenDoc Cookbook / Part - Appendixes

Appendix A - OpenDoc Utilities

This appendix describes some of the unsupported utilities provided with the Mac OS implementation of OpenDoc for the convenience of developers. The utilities described in this appendix are those used by SamplePart. They comprise classes, types, macros, and functions implemented in files with the following names:


These filenames also apply to header files containing class definitions, method declarations, and function, type, and macro definitions. The header files have the same filenames with the extension .h. To use these utilities, link the .cpp files into your library, and include the .h header files in your source files.

All of these utilities are supplied with the Mac OS implementation of OpenDoc on an "as-is" basis. They have not received the rigorous quality-assurance testing given to OpenDoc itself, and they are not part of the official OpenDoc API. Source code is provided, and you are welcome to modify the routines as necessary.
