Abstract: Techniques for porting operating systems of a first class whose representatives include operating systems implementing the POSIX standard to operating systems of a second class whose representatives include operating systems implementing the Win32 API. Processes belonging to operating systems of the first class are characterized by a single thread, parent-child relationships, and signal handlers that execute on the top of the stack; processes belonging to operating systems belonging to the second class have multiple threads, do not have parent-child relationships and do not necessarily execute their signal handlers at the top of the stack. Techniques are disclosed for implementing signal handling as required for operating systems of the first class and providing a signal to a parent process of the first class when one of its child processes terninates.
