NUTSCAN_ADD_OPTION_T(3)

NAME
nutscan_add_option_to_device, nutscan_add_commented_option_to_device - Add option data to the specified device.

SYNOPSIS

#include <nut-scan.h>

/* Add enabled option data to the specified device. */
void nutscan_add_option_to_device(
       nutscan_device_t * device,
       char * option_name,
       char * value);

/* Since libnutscan version 2.5.0:
 * Add option data to the specified device with an optional comment tag
 * for options suggested, but not currently enabled for actual use. */
void nutscan_add_commented_option_to_device(
       nutscan_device_t * device,
       char * option_name,
       char * value,
       char * comment_tag);

DESCRIPTION

The nutscan_device_t contains the following variables:

    nutscan_device_type_t   type;
    char *          driver;
    char *          alt_driver_names;
    char *          port;
    nutscan_options_t       opt;
    struct nutscan_device * prev;
    struct nutscan_device * next;

This is a double linked list of device. Each device is described by its type, its driver name, its port and any number of optional data.

The nutscan_add_option_to_device() adds an optional data in the given device. Optional data are made of an option_name and an associated value, and optionally a comment_tag. Copies of the option_name, value and comment_tag are stored in the device, so the caller can safely free all of the original strings used as arguments.

    Note

    A non-NULL value of the comment_tag makes the option not-enabled for current use. Depending on the output format, it may be either completely ignored, or rendered as a comment with this value as a prefix (a zero-length string "\0" may be passed to have no prefix).

Such options and their values may be further sanity-checked and reported as warnings by nutscan_display_sanity_check() dispatcher and its related methods which implement the logic of particular checks. This is used for example when generating ups.conf file content suggestions with nutscan_display_ups_conf_with_sanity_check() method.

NOTES

Technically, the function is currently defined in nutscan-device.h file.
