EVT_NFC_CX_WRITE_NCI_PACKET callback function (nfccx.h)

Called by the NFC CX to send a write packet to the client driver. The request code must match IOCTL_NFCCX_WRITE_PACKET.

Syntax

EVT_NFC_CX_WRITE_NCI_PACKET EvtNfcCxWriteNciPacket;

void EvtNfcCxWriteNciPacket(
  [in] WDFDEVICE Device,
  [in] WDFREQUEST Request
)
{...}

Parameters

[in] Device

A handle to a framework device object.

[in] Request

A handle to a framework request object.

Return value

None

Remarks

The client driver should not make any blocking calls when handling this function call. Any I/O processing must be handled on a separate thread or work-item (that is, the client driver should immediately return STATUS_PENDING and on completion invoke the completion handler).
