DESCRIPTION
|
||
|
|
-----------
|
||
|
|
|
||
|
|
These functions allow to manage variables of devices.
|
||
|
|
|
||
|
|
The *nutclient_get_device_variables()* function retrieve the list of variables names for a device.
|
||
|
|
The returned strarr must be freed by 'strarr_free'.
|
||
|
|
|
||
|
|
The *nutclient_get_device_rw_variables* function retrieve the list of read-write variables names for a device.
|
||
|
|
The returned strarr must be freed by 'strarr_free'.
|
||
|
|
|
||
|
|
The *nutclient_has_device_variable* function test if the specified variable is supported by the device.
|
||
|
|
Return 1 is supported and 0 if not.
|
||
|
|
|
||
|
|
The *nutclient_get_device_variable_description* function retrieve the variable description, if any.
|
||
|
|
The resturned string must be freed.
|
||
|
|
|
||
|
|
The *nutclient_get_device_variable_values* returns variable values (generally only one).
|
||
|
|
The returned strarr must be freed by 'strarr_free'.
|
||
|
|
|
||
|
|
The *nutclient_set_device_variable_value* intend to set the value of the specified variable.
|
||
|
|
|
||
|
|
The *nutclient_set_device_variable_values* intend to set multiple values of the specified variable.
|
||
|
|
|
||
|
|
'dev' is the device name.
|
||
|
|
|
||
|
|
'var' is the variable name.
|
||
|
|
|
||
|
|
'value' is the variable value.
|
||
|
|
|
||
|
|
'values' is the variable array of values.
