The IHV Extensions DLL calls the Dot11ExtSetDefaultKey function to add or delete a cipher key from the default key or per-station default key tables of the wireless LAN (WLAN) adapter. For more information about these key types, see 802.11 Cipher Key Types.
Syntax
DOT11EXT_SET_DEFAULT_KEY Dot11extSetDefaultKey;
DWORD Dot11extSetDefaultKey(
[in, optional] HANDLE hDot11SvcHandle,
[in] PDOT11_CIPHER_DEFAULT_KEY_VALUE pKey,
[in] DOT11_DIRECTION dot11Direction
)
{...}
Parameters
[in, optional] hDot11SvcHandle
The handle used by the operating system to reference the WLAN adapter. This handle value was specified through a previous call to the Dot11ExtIhvInitAdapter IHV Handler function.
[in] pKey
A pointer to a DOT11_CIPHER_DEFAULT_KEY_VALUE structure, which defines the cipher key.
[in] dot11Direction
A DOT11_DIRECTION value that specifies whether the key can be used only for received packets (DOT11_DIR_INBOUND) or both received and sent packets (DOT11_DIR_BOTH).
Return value
If the call succeeds, the function returns ERROR_SUCCESS. Otherwise, it returns an error code defined in Winerror.h.
Remarks
A call to the Dot11ExtSetDefaultKey function results in a set request of the OID_DOT11_CIPHER_DEFAULT_KEY object identifier to the WLAN adapter.
A default cipher key is defined by setting the MacAddr member of the DOT11_CIPHER_DEFAULT_KEY_VALUE structure to a value of 0x000000000000. A per-station default cipher key is defined by setting the MacAddr member to a valid unicast media access control (MAC) address.
A cipher key is deleted from the adapter's key tables if the bDelete member of the DOT11_CIPHER_DEFAULT_KEY_VALUE structure is set to TRUE.
