.SH "NAME"
nutscan_add_device_to_device \- Concatenate two devices structure\&.
.SH "SYNOPSIS"
.sp
.nf
#include <nut\-scan\&.h>
.fi
.sp
.nf
nutscan_device_t * nutscan_add_device_to_device(nutscan_device_t * first, nutscan_device_t * second);
.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_device_to_device()\fR concatenates \fIfirst\fR and \fIsecond\fR devices to a unique device\&. No new device is created, the two linked list are simply linked to each other\&. So \fIfirst\fR and \fIsecond\fR devices are likely to be modified by this function\&.
.SH "RETURN VALUE"
.sp
The \fBnutscan_add_device_to_device()\fR functions returns a pointer to a device containg both passed devices\&. Note that it\(cqs not a new device, so it is either \fIfirst\fR or \fIsecond\fR which is returned\&.
