/*
* DRVCTLCOMMAND documentation
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~
*
* Generic ioctl that takes a dictionary as an argument (specifies the
* command and arguments) and returns a dictionary with the results.
*
* Command arguments are structured like so:
*
* <dict>
* <key>drvctl-command</key>
* <string>...</string>
* <!-- optional arguments -->
* <key>drvctl-arguments</key>
* <dict>
* <!-- arguments vary with command -->
* </dict>
* </dict>
*
* Results are returned like so:
*
* <dict>
* <key>drvctl-error</key>
* <!-- 0 == success, otherwise an errno value -->
* <integer>...</integer>
* <!-- optional additional error message -->
* <key>drvctl-error-message</key>
* <string>...</string>
* <!-- optional results dictionary -->
* <key>drvctl-result-data</key>
* <dict>
* <!-- results vary with command -->
* </dict>
* </dict>
*
*
* Commands recognized by DRVCTLCOMMAND
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*
* get-properties
*
* Arguments:
*
* <dict>
* <key>device-name</key>
* <string>...</string>
* </dict>
*
* Results:
* <dict>
* <!-- contents of device's properties dictionary -->
* </dict>
