Description

[0001] related application [0002] This application relates to jointly pending, jointly owned and commonly assigned US Patent Application No. (serial number undecided) filed on December 15, 2003, and the attorney's case number is No.ARC9-2003-0089. technical field [0003] The present invention relates to operating systems, and more particularly to methods and systems for accessing at least one object file within a computer system having an operating system that implements file locking while the file is open. Background technique [0004] The Microsoft Windows (hereinafter referred to as "Windows") kernel and Windows programs have the ability to prevent files from being opened and read by other processes. This is achieved by opening a file and not giving other processes special permissions (such as read). As long as the process keeps the file open, other processes obey the permissions allowed by the process. Attempts by other processes to open such a file will result in a...
