Module: XDo::Drive

Extended by:
Open3
Defined in:
lib/xdo/drive.rb

Overview

Some methods to interact with CD (and DVD, of course) drives. The value of the drive parameter of many methods can be either a mount point or a device file like scd0.

If you don’t pass in a drive name, the returnvalue of #default will be used.
