.SH "NAME"
nutscan_scan_nut \- Scan network for available NUT services\&.
.SH "SYNOPSIS"
.sp
.nf
#include <nut\-scan\&.h>
#include <unistd\&.h> /* useconds_t */
.fi
.sp
.nf
nutscan_device_t * nutscan_scan_nut(

.SH "DESCRIPTION"
.sp
The \fBnutscan_scan_nut()\fR function try to detect available NUT services and their associated devices\&. It issues a NUT request on every IP ranging from \fIstartIP\fR to \fIstopIP\fR\&. \fIstartIP\fR is mandatory, \fIstopIP\fR is optional\&. Those IP arguments may be either IPv4 or IPv6 addresses or host names\&.
.sp
You MUST call \fBnutscan_init\fR(3) before using this function\&.
.sp
A specific \fIport\fR number may be passed, or NULL to use the default NUT port\&.
.sp
This function waits up to \fIusec_timeout\fR microseconds before considering an IP address does not respond to NUT queries\&.
.SH "RETURN VALUE"
.sp
The \fBnutscan_scan_nut()\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\&.
