LIBNUTCLIENT_VARIABLES(3)
=========================
NAME
----
libnutclient_variables, nutclient_get_device_variables,
nutclient_get_device_rw_variables, nutclient_has_device_variable,
nutclient_get_device_variable_description, nutclient_get_device_variable_values,
nutclient_set_device_variable_value, nutclient_set_device_variable_values -
Variable related functions in Network UPS Tools high-level client access library
SYNOPSIS
--------
#include <nutclient.h>
typedef void* NUTCLIENT_t;
strarr nutclient_get_device_variables(NUTCLIENT_t client, const char* dev);
strarr nutclient_get_device_rw_variables(NUTCLIENT_t client, const char* dev);
int nutclient_has_device_variable(NUTCLIENT_t client, const char* dev, const char* var);
char* nutclient_get_device_variable_description(NUTCLIENT_t client, const char* dev, const char* var);
strarr nutclient_get_device_variable_values(NUTCLIENT_t client, const char* dev, const char* var);
void nutclient_set_device_variable_value(NUTCLIENT_t client, const char* dev, const char* var, const char* value);
void nutclient_set_device_variable_values(NUTCLIENT_t client, const char* dev, const char* var, const strarr values);
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.
