NUTSCAN_INIT(3)                   NUT Manual                   NUTSCAN_INIT(3)

NAME
       nutscan_init - Initialize the nutscan library.

SYNOPSIS
               #include <nut-scan.h>

               void nutscan_init(void);

DESCRIPTION
       The nutscan_init() function must be called at least once before using
       any other function of the nutscan library.

       It updates the following global variables which can be used by nutscan
       library user to know which scan methods are available at run-time.

       This depends on further libraries installed on the system:

       o   nutscan_avail_avahi = 1: AVAHI NUT scan is available

       o   nutscan_avail_ipmi = 1: IPMI scan is available

       o   nutscan_avail_nut = 1: "Old" NUT method is available

       o   nutscan_avail_nut_simulation = 1: NUT simulation devices method is
           available

       o   nutscan_avail_snmp = 1: SNMP method is available

       o   nutscan_avail_usb = 1: USB method is available

       o   nutscan_avail_xml_http = 1: XML HTTP method is available

       Note that if a method is reported as unavailable by those variables,
       the call to the corresponding nutscan_scan_* function will always
       return NULL.

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