"execute a command" ioctl that takes a dictionary as an argument (specifying the command and arguments) and returns a dictionary with the results (error code, optional error message, optional result data). - Define and implement a "get-properties" command for DRVCTLCOMMAND that returns the properties dictionary of the specified device. - Add a -p flag to drvctl(8) to fetch and display the properties of the specified device. This is a great example of how to use prop_dictionary_sendrecv_ioctl(). |
