NAME
       nutscan - Network UPS Tools (NUT) device discovery library

DESCRIPTION
       The Network UPS Tools (NUT) nutscan library provides the same discovery
       related features that are also offered by nut-scanner(8).

       It enables the discovery of supported NUT devices (USB, SNMP, Eaton
       XML/HTTP and IPMI) and NUT servers (using Avahi, or the classic
       connection method).

DISCOVERY FUNCTIONS
       First, include the required header file:

           #include <nut-scan.h>

       Then, to discover new devices, use the appropriate function:

       o   nutscan_scan_usb(3) for supported USB devices,

       o   nutscan_scan_snmp(3) for supported SNMP agents,

       o   nutscan_scan_xml_http(3) for Eaton Network Management Card,

       o   nutscan_scan_nut(3) for NUT servers (upsd), using the classic
           method,

       o   nutscan_scan_avahi(3) for NUT servers (upsd), using the mDNS
           (Avahi) method,

       o   nutscan_scan_ipmi(3) for supported IPMI PSU.

       All of these functions return a list of devices found, using the
       nutscan_device_t structure. This structure is described in
       nutscan_add_device_to_device(3).

       Helper functions are also provided to output data using standard
       formats:

       o   nutscan_display_parsable(3) for parsable output,

       o   nutscan_display_ups_conf(3) for ups.conf style.

ERROR HANDLING
       There is currently no specific mechanism for error handling.
