These functions allow to manage instant commands of devices.

•The nutclient_get_device_commands() function retrieves the list of command names for a device.

The returned strarr must be freed by strarr_free.

•The nutclient_has_device_command function tests if the specified command is supported by the device.

Return 1 if supported and 0 if not.

•The nutclient_get_device_command_description function retrieves the command description, if any.

The returned string must be freed by free(3) (see libnutclient_general(3)).

•The nutclient_execute_device_command intends to execute the instant command, with an optional parameter.

Common arguments:

•dev is the device name.
•cmd is the instant command name.
