Application Conversion Of Source Data, Tue Jun 07 16:02:08 EDT 2011

A method leverages the file format information used by a target application to convert a source dataset into an encoding usable by the target application without converting the source dataset before migration and without modifying the target application. The source data when on the source system has random portions of various data types that are encoded in a source encoding based on data type. The target application, which typically processes data encoded in a target encoding that is based on data type, is able to process the source data despite the source encoding using file format information and a modified compiler library.

Porting POSIX-conforming operating systems to Win32 API-conforming operating systems, Tue Mar 16 18:09:08 EST 2004

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. Processes of the second class adapted for implementing processes of the first class are disclosed, as well as implementations of the POSIX fork and exec functions using those processes.
