nutscan_scan_xml_http_range - Man Page

Scan network for XML/HTTP devices.

Synopsis

#include <nut-scan.h>
#include <unistd.h> /* useconds_t */
nutscan_device_t * nutscan_scan_xml_http_range(
       const char * start_ip,
       const char * end_ip,
       useconds_t usec_timeout,
       nutscan_xml_t * sec)

Description

The nutscan_scan_xml_http_range() function tries to detect NUT compatible XML/HTTP devices.

If start_ip is NULL, the function does this by issuing a broadcast message on currently configured network interfaces.

Otherwise, it queries every IP ranging from start_ip to stop_ip. Those IP arguments may be either IPv4 or IPv6 addresses or host names.

It waits up to usec_timeout microseconds for a response from potential devices.

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

Return Value

The nutscan_scan_xml_http_range() 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.
