Windows Driver Kit DDI reference (ns-windot11-_dot11_mac_address)

Important The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.

The DOT11_MAC_ADDRESS array defines an IEEE media access control (MAC) address.

The MAC address in unicast, multicast, or broadcast format.

typedef struct _DOT11_MAC_ADDRESS {
  UCHAR ucDot11MacAddress[6];
} DOT11_MAC_ADDRESS, *PDOT11_MAC_ADDRESS;

A unicast MAC address uniquely identifies a station on a WLAN. A MAC address is defined as a unicast address if the following is true:

(DOT11_MAC_ADDRESS[0] & 0x01 == 0)

A multicast MAC address uniquely identifies a group of stations on a WLAN. A MAC address is defined as a multicast address if the following is true:

(DOT11_MAC_ADDRESS[0] & 0x01 == 1)

A broadcast MAC address identifies all stations on a WLAN. The broadcast MAC address is 0xFFFFFFFFFFFF.

The PDOT11_MAC_ADDRESS type is defined as a pointer to the DOT11_MAC_ADDRESS type as follows:

typedef DOT11_MAC_ADDRESS  *PDOT11_MAC_ADDRESS;
