ChorusOS 4.x Legacy applications

An API developed for release 4.x of the ChorusOS operating system, to support applications developed with POSIX-like functionality without being fully POSIX-compliant. Now superseded by the full POSIX implementation described above, but retained for reasons of backward compatibility.

The POSIX processes and the ChorusOS actors combine to provide a rich range of functionality. However, the two APIs are mutually exclusive. For details of the implementations of these APIs in release 5.0 of the ChorusOS operating system, see API(5FEA).
