/ Resources / C++ Version /

The following provides a summary of the C++ version of RCOS as of the end of 1995.

The files and classes used have been divided into a 13 sections. Of the 13 sections, ?? will probably not be used in the Java port of RCOS including

• support classes, graphics, data structures
• platform abstraction layer
• preferences and application framework
• animation and display

The concepts used in the remainder of the sections will be used but are liable to be heavily modified.

Main function and global definitions

Files	rcos.cc Main (Supervisor) module rcos.hh Common header definitions
