NAME

       nutscan_scan_nut - Scan network for available NUT services.

SYNOPSIS

               #include <nut-scan.h>
               #include <unistd.h> /* useconds_t */

               nutscan_device_t * nutscan_scan_nut(
                       const char * startIP,
                       const char * stopIP,
                       const char * port,
                       useconds_t usec_timeout);

               nutscan_device_t * nutscan_scan_ip_range_nut(
                       nutscan_ip_range_list_t * irl,
                       const char * port,
                       useconds_t usec_timeout);

DESCRIPTION

       The nutscan_scan_nut() and nutscan_scan_ip_range_nut() functions try to detect available NUT services and
       their associated devices. The former issues a NUT request on every IP ranging from startIP to stopIP,
       where startIP is mandatory and stopIP is optional (one startIP address is scanned if stopIP is NULL);
       while the latter can walk several IP address ranges represented by a nutscan_ip_range_list_t structure.

       Those IP arguments may be either IPv4 or IPv6 addresses or host names.

       You MUST call nutscan_init(3) before using this function.

       A specific port number may be passed, or NULL to use the default NUT port.

       This function waits up to usec_timeout microseconds before considering an IP address does not respond to
       NUT queries.

RETURN VALUE

       The nutscan_scan_nut() function returns a pointer to a nutscan_device_t structure containing all found
       devices or NULL if an error occurs or no device is found.
