ABSTRACT:
A file accessing scheme allows logical files to be processed outside of the native operating system and its logical I/O subsystem. When an application program wants to process a file outside of the native operating system, a file information block is built with a special type of file designated as “virtual.” A pointer is provided within the file information block to a handler. The handler is a library that is external to the native operating system. The library processes the file without using the native operating system. Upon completion of the processing, the handler returns the operation results to the file information block and control is transferred back to the application program.
