SYNOPSIS

#include <nutclient.h>

typedef void* NUTCLIENT_t;

typedef char** strarr;

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 retrieves the list of variables names for a device. The returned strarr must be freed by strarr_free.

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.

The nutclient_has_device_variable function tests if the specified variable is supported by the device. Return 1 is supported and 0 if not.

The nutclient_get_device_variable_description function retrieves the variable description, if any. The returned 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 intends to set the value of the specified variable.

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