A COMPUTING SYSTEM HAVING USER MODE CRITICAL SYSTEM ELEMENTSAS SHARED LIBRARIES

摘要

A computing system and architecture is provided that affects and extends services exported through application libraries. The system has an operating system having an operating system kernel having OS critical system elements (OSCSEs) for running in kernel mod e; and, a shared library having critical system elements (SLCSEs) stored within the shared library for use by the software applications in user mode. The SLCSEs stored in the shar ed library are accessible to the software applications and when accessed by a software application forms a part of the software application. When an instance of an SLCSE provided to a n application from the shared library it is run in a context of the software application without being shared with other software applications. The other applications running under the operating system each have use of a unique instance of a corresponding critical system elemen t fox performing essentially the same function, and can be run simultaneously.
