NUTSCAN(3) NUT Manual NUTSCAN(3)
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:
· nutscan_scan_usb(3) for supported USB devices,
· nutscan_scan_snmp(3) for supported SNMP agents,
· nutscan_scan_xml_http(3) for Eaton Network Management Card,
· nutscan_scan_nut(3) for NUT servers (upsd), using the classic
method,
· nutscan_scan_avahi(3) for NUT servers (upsd), using the mDNS
(Avahi) method,
· 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:
· nutscan_display_parsable(3) for parsable output,
· nutscan_display_ups_conf(3) for ups.conf style.
ERROR HANDLING
There is currently no specific mechanism for error handling.
