INativeListener.OnReleaseFrameLengthControl Method

Native (C++):

HRESULT OnReleaseFrameLengthControl ( _FILETIME * fTime,void * pData,unsigned long Size,unsigned short Interface) ;

Parameters

fTime The time of the event. pData Pointer to a USBPACKET. Use it to manually parse all fields. See MFCSample for more details. Size Total size of USBPACKET and all payload data. Equals to nSize variable:

C++

          USBPACKET packet;
          ULONG nSize = packet->Size;

          USBPACKET_URB* pUrb = (USBPACKET_URB*)packet;
          ATLASSERT(pUrb->Size==nSize);

Interface Specifies the device-defined index of the interface descriptor being retrieved.

Return Value

S_OK or standard OLE error code.

Remarks

Fired when URB packet with urb.UrbHeader.Function=URB_FUNCTION_RELEASE_FRAME_LENGTH_CONTROL is received. See _URB_CONTROL_GET_INTERFACE_REQUEST for more details. The library decodes several parameters from this packet (see above).
