Dot11ExtIhvReceivePacket (Compact 2013)

3/26/2014

The operating system calls this function to forward a packet, received by the wireless LAN (WLAN) adapter, to the IHV Extensions DLL for processing.

Syntax

DWORD WINAPI Dot11ExtIhvReceivePacket(
    HANDLE hIhvExtAdapter,
    DWORD dwInBufferSize,
    LPVOID pvInBuffer
);

hIhvExtAdapter
[in] The handle that is used by the IHV Extensions DLL to reference the WLAN adapter. This handle value was specified through a previous call to the Dot11ExtIhvInitAdapter IHV Handler function.

dwInBufferSize
[in] The length, in bytes, of the received packet referenced by the pvInBuffer parameter.

pvInBuffer
[in] A pointer to a buffer, allocated by the operating system, which contains the packet data. This includes the 802.11 media access control (MAC) header.

If the call succeeds, the function returns ERROR_SUCCESS. Otherwise, it returns an error code defined in Winerror.h.

The operating system calls the Dot11ExtIhvReceivePacket function when the following occur:

The WLAN adapter receives a packet and the Native 802.11 miniport driver, which manages the adapter, indicates the packet to the operating system.
The packet’s IEEE EtherType matches an entry in the list of EtherTypes specified by the IHV Extensions DLL through a call to the Dot11ExtSetEtherTypeHandling function.
