# nutscan\_scan\_xml\_http\_range(3)

Scan network for XML/HTTP devices.

## NAME

nutscan\_scan\_xml\_http\_range - 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)
        nutscan_device_t * nutscan_scan_ip_range_xml_http(
                nutscan_ip_range_list_t * irl,
                useconds_t usec_timeout,
                nutscan_xml_t * sec)
```

## DESCRIPTION

The **nutscan\_scan\_xml\_http\_range()** and **nutscan\_scan\_ip\_range\_xml\_http()** functions try to detect NUT compatible XML/HTTP devices.

If *start\_ip* for the former or *irl* for the latter are NULL, the respective function does this by issuing a broadcast message on all currently configured network interfaces.

Otherwise, the former queries every IP ranging from *start\_ip* to *stop\_ip*, , 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.

It waits up to *usec\_timeout* microseconds for a response from potential devices.

You MUST call [**nutscan\_init**(3)](/nutscan_init/3.md) 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.
