.SH "DESCRIPTION"
.sp
2012-08-13 00:39:31 +03:00
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\&.
2011-09-29 21:14:46 +03:00
.sp
2012-01-24 12:22:33 +02:00
You MUST call \fBnutscan_init\fR(3) before using this function\&.
.sp
2022-07-10 10:23:45 +03:00
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\&.
2011-09-29 21:14:46 +03:00
.SH "RETURN VALUE"
.sp
2022-07-10 10:23:45 +03:00
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\&.
