.SH "NAME"
nutscan_init \- Initialize the nutscan library\&.
.SH "SYNOPSIS"
.sp
.nf
        #include <nut\-scan\&.h>

        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 further libraries installed on the system:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

nutscan_avail_xml_http = 1: XML HTTP method is available
.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\&.
