Detailed Description

OS COFFEE Unix implementation.

This class implements Cooperative File Functions under unix enviroments.

Unix is usually very cooperative towards threading, and this means that calls inside this class are usually very simple inline calls to unix system calls.

You can access this class with the typedef OSFileFunc.
