Abstract
A file system locking mechanism is provided which prevents the errors which arise when race conditions occur in a multitasking system. Atomic operators are utilized to perform certain operations for the creation and renaming of files and directories in the file system wherein if a race condition occurs, the atomic operations fail and the file creation process is halted to a predetermined state whereby the errors which occur during race conditions are prevented.
