.SH "NAME"
nutscan_init \- Initialize the nutscan library\&.
.SH "SYNOPSIS"
.sp
.nf
#include <nut\-scan\&.h>
.fi
.sp
.nf
void nutscan_init(void);
.fi
.SH "DESCRIPTION"
.sp
The \fBnutscan_init()\fR function must be called at least once before using any other function of the nutscan library\&.
.sp
It updates the following global variables which can be used by nutscan library user to know which scan methods are available at run\-time\&.
.sp
This depends on the libraries installed on the system:
.sp
.if n \{\
.RS 4
.\}
.nf
nutscan_avail_avahi = 1 : AVAHI scan is available
nutscan_avail_ipmi = 1 : IPMI scan is available
nutscan_avail_nut = 1 : Old NUT method is available
nutscan_avail_snmp = 1 : SNMP method is available
nutscan_avail_usb = 1 : USB method is available
nutscan_avail_xml_http = 1 : XML HTTP method is available
.fi
.if n \{\
.RE
.\}
.sp
Note that if a method is reported as unavailable by those variables, the call to the corresponding nutscan_scan_* function will always return NULL\&.
.SH "NOTES"
.sp
Technically, the function is currently defined in \fInutscan\-init\&.h\fR file\&.
