typdef in iw_handler.h

[Bond <jamesbond.2k.g@xxxxxxxxx>]

I have used typedef in my C programs previously many times.
So it is not new to me

For example consider following typedef
struct var {
    int data1;
    int data2;
    char data3;
};

typedef struct var newtype;
then we can use newtype instead of struct var.

Now see this
typedef int (*iw_handler)(struct net_device *dev, struct iw_request_info *info,
                          union iwreq_data *wrqu, char *extra);

above is line number 314 in include/net/iw_handler.h

I was not able to understand what is being typedef'd here?
