This project is an implementation of a small, but fully functional multithreaded operating system kernel with time sharing. More precisely, it contains the source code of kernel's thread management subsystem.

User application (user.cpp) and the kernel are compiled and linked into a single console application (m-kernel.exe). Static library lib/APPLICAT.lib contains the implementation of system's scheduler. You can see scheduler's interface in scheduler.h.

The full project specification can be found here (Serbian language only).

This project uses a very old C++ compiler, Borland C++ Compiler (BCC), version 3.1, from 1992. BCC provides a simple way of tempering with interrupt vector table (IVT) on MS DOS (Microsoft Disk Operating System), which is necessary in order to implement time-sharing functionality.
