.SH "NAME"
nutscan_add_option_to_device \- Add option data to the specified device\&.
.SH "SYNOPSIS"
.sp
.nf
#include <nut\-scan\&.h>
.fi
.sp
.nf
void nutscan_add_option_to_device(
       nutscan_device_t * device,
       char * option_name,
       char * value);
.fi
.SH "DESCRIPTION"
.sp
The nutscan_device_t contains the following variables:
.sp
.if n \{\
.RS 4
.\}
.nf
nutscan_device_type_t   type;
char *          driver;
char *          port;
nutscan_options_t       opt;
struct nutscan_device * prev;
struct nutscan_device * next;
.fi
.if n \{\
.RE
.\}
.sp
This is a double linked list of device\&. Each device is described by its type, its driver name, its port and any number of optional data\&.
.sp
The \fBnutscan_add_option_to_device()\fR adds an optional data in the given device\&. Optional data are made of an \fIoption_name\fR and an associated \fIvalue\fR\&. Copies of \fIoption_name\fR and \fIvalue\fR are stored in the device, so the caller can safely free both of the original strings used as arguments\&.
.sp
Such options and their values may be further sanity\-checked and reported as warnings by \fBnutscan_display_sanity_check()\fR dispatcher and its related methods which implement the logic of particular checks\&. This is used for example when generating \fIups\&.conf\fR file content suggestions with \fBnutscan_display_ups_conf_with_sanity_check()\fR method\&.
.SH "NOTES"
.sp
Technically, the function is currently defined in \fInutscan\-device\&.h\fR file\&.
