Hi, I'm writing a linux kernel module and I'm trying to use the get_wireless_stats function , but it keeps printing an error saying :
"dereferencing pointer to incomplete type"

here's how I used it, can anyone tell me what's going on?

struct net_device *dev;
struct iw_statistics *wi_stats;


wi_stats = dev->wireless_handlers->get_wireless_stats(dev);

Incompete type is a type that is declared but not defined (in case of struct types). the problem here was that wireless_handlers is declared in net_device.h but not defined,it's defined in net/iw_handler.h. All I had to do was include it and the error disappeared!
