Windows Driver Kit DDI reference (ns-windot11-_dot11_send_provision_discovery_response_parameters)

_DOT11_SEND_PROVISION_DISCOVERY_RESPONSE_PARAMETERS structure

Description

[!Important] WiFiCx is the new Wi-Fi driver model released in Windows 11. We recommend that you use WiFiCx to take advantage of the latest features. The WDI driver model is now in maintenance mode and will only receive high priority fixes.

The parameters for a response to a provision discovery request are specified in a DOT11_SEND_PROVISION_DISCOVERY_RESPONSE_PARAMETERS structure. This structure is sent with an OID_DOT11_WFD_SEND_PROVISION_DISCOVERY_RESPONSE request to the miniport.

Members

`Header`

The type, revision, and size of the DOT11_SEND_PROVISION_DISCOVERY_RESPONSE_PARAMETERS structure. The required settings for the members of Header are the following.

Member	Setting
Type	NDIS_OBJECT_TYPE_DEFAULT
Revision	DOT11_SEND_PROVISION_DISCOVERY_RESPONSE_PARAMETERS_REVISION_1
Size	DOT11_SIZEOF_SEND_PROVISION_DISCOVERY_RESPONSE_PARAMETERS_REVISION_1

`ReceiverDeviceAddress`

The address of the device that transmitted the provision discovery request packet.

`DialogToken`

The dialog token received from the provision discovery request packet. This token must be used in the provision discovery response packet.

`RequestContext`

The context data given initially by the NDIS_STATUS_DOT11_WFD_RECEIVED_PROVISION_DISCOVERY_REQUEST indication.

`uSendTimeout`

The maximum time, in milliseconds, allowed to send the provision discovery response. If the time-out expires before the miniport has successfully transmitted the provision discovery response, it should indicate the NDIS_STATUS_DOT11_WFD_PROVISION_DISCOVERY_RESPONSE_SEND_COMPLETE with a failure status.

`uIEsOffset`

The offset, in bytes, of the array of additional information elements (IEs) the Wi-Fi Direct (WFD) port must add to the provision discovery response packet. This offset is from the start of the buffer that contains this structure.

`uIEsLength`

The length, in bytes, of the array of IEs provided at uIEsOffset.
