       libnutclient_commands, nutclient_get_device_commands, nutclient_has_device_command,

SYNOPSIS

       #include <nutclient.h>

       typedef void* NUTCLIENT_t;

       typedef char** strarr;

       strarr nutclient_get_device_commands(
               NUTCLIENT_t client,
               const char* dev);

       int nutclient_has_device_command(
               NUTCLIENT_t client,
               const char* dev, const char* cmd);

       char* nutclient_get_device_command_description(
               NUTCLIENT_t client,
               const char* dev, const char* cmd);

       void nutclient_execute_device_command(
               NUTCLIENT_t client,
               const char* dev, const char* cmd,
               const char* param="");

DESCRIPTION

       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 is supported and 0 if not.

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

           The returned string must be freed.

       •   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.
