Abstract: A multiprocessor that includes a virtual file system providing a file system interface to user application code. This interface allows users to access files in many types of file systems in a consistent, file system-independent manner. In a preferred embodiment, the higher interface of the file system is the Posix file system interface, though it can be any file system interface supporting the capabilities required by a user process. The Posix file system supports regular files, pipes, fifos and special files. A pipe server, a pipe library and a name server together implement the fifo semantics required by the Posix standard for Posix processes. The present invention provides these fifo capabilities to any process which uses the Posix interfaces.
