If you've gotten this far, you've probably noticed that the examples in the previous section are all in C. Don't despair- Pat Welch has added excellent C++ support to legOS. Unfortunately, at the moment, this is only available in CVS, but it will be available more easily in version 0.2.5 (whenever that is released.) To see how to use CVS, read the section called Getting legOS Development Versions From CVS.
To see how to use the C++, Pat has written a large set of demo code, available in the demo/c++/ directory.
