These functions allow to manage variables of devices.

• The nutclient_get_device_variables() function retrieves the list of variables names for a device.

  The returned strarr must be freed by strarr_free (see libnutclient_general(3)).

• The nutclient_get_device_rw_variables function retrieves the list of read-write variables names for a device.

  The returned strarr must be freed by strarr_free (see libnutclient_general(3)).

• The nutclient_has_device_variable function tests if the specified variable is supported by the device.

  Return 1 if supported and 0 if not.

• The nutclient_get_device_variable_description function retrieves the variable description, if any.

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

• The nutclient_get_device_variable_values returns variable values (generally only one).

  The returned strarr must be freed by strarr_free (see libnutclient_general(3)).

• The nutclient_set_device_variable_value intends to set the value of the specified variable.
• The nutclient_set_device_variable_values intends to set multiple values of the specified variable.

Common arguments:

• dev is the device name.
• var is the variable name.
• value is the variable value.
• values is the variable array of values.
