.SH "DESCRIPTION"
.sp
The \fBnutscan_scan_xml_http_range()\fR and \fBnutscan_scan_ip_range_xml_http()\fR functions try to detect NUT compatible XML/HTTP devices\&.
.sp
If \fIstart_ip\fR for the former or \fIirl\fR for the latter are NULL, the respective function does this by issuing a broadcast message on all currently configured network interfaces\&.
.sp
Otherwise, the former queries every IP ranging from \fIstart_ip\fR to \fIstop_ip\fR, , where \fIstartIP\fR is mandatory and \fIstopIP\fR is optional (one \fIstartIP\fR address is scanned if \fIstopIP\fR is NULL); while the latter can walk several IP address ranges represented by a nutscan_ip_range_list_t structure\&.
.sp
Those IP arguments may be either IPv4 or IPv6 addresses or host names\&.
.sp
It waits up to \fIusec_timeout\fR microseconds for a response from potential devices\&.
.sp
You MUST call \fBnutscan_init\fR(3) before using this function\&.
.SH "RETURN VALUE"
.sp
The \fBnutscan_scan_xml_http_range()\fR 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\&.
