This is the reference guide for VMime, available since release 0.8.0. It contains more than 60 pages of documentation in PDF format.
Read the VMime Book: A Developer's Guide to VMime.
WARNING! This documentation may not be complete. I try to maintain it up-to-date but it is possible some example code or information might be outdated and/or new features not yet documented.
This is the documentation generated by Doxygen from source code comments. Doxygen-generated documentation is always up-to-date (in regard to the current release).
If you can't find some information, take a look at the source code comments (code is quite well documented). You can also try on VMime forums on SourceForge.
Old, HTML-based, documentation is available here.
It will not be updated anymore.
