.SH "NAME"
nutscan_scan_avahi \- Scan network for NUT services via mDNS
.SH "SYNOPSIS"
.sp
.nf
#include <nut\-scan\&.h>
#include <unistd\&.h> /* useconds_t */
.fi
.sp
.nf
nutscan_device_t * nutscan_scan_avahi(useconds_t usec_timeout);
.fi
.SH "DESCRIPTION"
.sp
The \fBnutscan_scan_avahi()\fR function tries to detect the NUT service via mDNS, and its associated devices\&. It uses the Avahi library to do so\&.
.sp
You MUST call \fBnutscan_init\fR(3) before using this function\&.
.sp
This function can query perspective IP addresses using NUT protocol, and in this case it waits up to \fIusec_timeout\fR microseconds before considering an IP address to be unresponsive\&.
.SH "RETURN VALUE"
.sp
The \fBnutscan_scan_avahi()\fR function returns a pointer to a nutscan_device_t structure containing all found devices\&.
.sp
It returns NULL if an error occurs, or if no device is found\&.
