Detailed Description

These routines are called via the proc ptr in the ubik_dbase structure.

They provide access to the physical disk, by converting the file numbers being processed ( >= 0 for user data space, < 0 for ubik system files, such as the log) to actual pathnames to open, read, write, truncate, sync, etc.

(

struct ubik_dbase *

adbase

)

Get number of dbase files.
