This section covers the organization of the file system at runtime. MMFS is divided into a number of modules, each of which covers a specific area of functionality. The following sections cover these in detail.

FILEIO Interface

This module provides the interface to the FILEIO package to present a standard file system interface. This is achieved by exporting a filesystem table entry for the "mmfs" filesystem type. In fact two filesystems are exported, "mmfs" and "mmfs.format". These behave identically except that "mmfs.format" causes the filesystem to be reformatted as part of the mount operation.
