\section MsgHandling Extending CAPWAP
Probably the easies way to explain, how to extend the CAPWAP, is to show an example.\n
Here we go ...
\subsection SimpleExample A Simple Example
Imagine you whant to implement a new vendor specific message element called 
"WTP LED Status and Color". In the real world this could be a message element, that 
is  used by a WTP to indicate it's LED status, and sent by the AC to set the WTP's
LED status.\n
There might be a specification where the message element is idefined as follows:


\code

Vendor Specific Element - WTP LED Status and Color

   0                   1                   
   0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |    Status     |   Color       |
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Type: 17
Length: 2
 
Status: 
   0=off
   1=on
   2=flashing

Color:
   0=blue
   1=red
   2=gren
\endcode

The first thing we have now to do, ist to define an item ID, that is interlnally 
used by AC-Tube to store and find data associated with this message element. 
This ID is simply a system-wide unique string constant.\n
So let's create a file "mycapwap.c" and define the ID.

\code 

const char CW_MYITEM_WTP_LED_STATUS_AND_COLOR[]="wtp_led_status_and_color";

\endcode

The item ID is also used to identify message element data stored in a SQL 
database or in json objects.\n
Next we should provide some information about our item, which is done by
creating an item definition, described by structure #cw_itemdef.\n
Looking at the specification of our message element we see that the value
is built of two bytes, which can be represented as word. There is a 
pre-defined type MBAG_WORD which we will use.
\code
#include "capwap/mbag.h"
const char CW_MYITEM_WTP_LED_STATUS_AND_COLOR[]="wtp_led_status_and_color";

struct cw_itemdef_t myitemdefs[] = {
	{CW_MYITEM_WTP_LED_STATUS,CW_ITEM_NONE,MBAG_WORD}
};


\endcode
