        SYNTAX

        #include <disktab.h>


        DESCRIPTION

        Disktab is a simple datebase which describes disk geometries and
        disk partition characteristics.  The format is patterned after
        the termcap(5) terminal data base.  Entries in disktab consist of
        a number of `:' separated fields.  The first entry for each disk
        gives the names which are known for the disk, separated by `|'
        characters.  The last name given should be a long name fully
        identifying the disk.

        The following list indicates the normal values stored for each
        disk entry.

        rm    num   Disk revolutions per minute (usually 3600)
        se    num   Sector size in bytes
