  DWORD cbInstanceData,
  LPVOID pPropData,
  DWORD cbPropData
);

Parameters

guidPropSet

[in] Property set GUID.

dwPropID

[in] Identifier of the property within the property set.

pInstanceData

[in, size_is(cbInstanceData)] Pointer to a buffer that contains instance data for the property.

cbInstanceData

[in] Size of the pInstanceData buffer, in bytes.

pPropData

[in, size_is(cbPropData)]  Pointer to a buffer that contains the value of the property.

Remarks

  • **Note   **Another interface by this name exists in the dsound.h header file. The two interfaces are not compatible. The IKsControl interface, documented in the DirectShow DDK, is now the recommended interface for passing property sets between WDM drivers and user mode components.

Requirements

Header: Include Ks.h, Ksproxy.h. You must include Ks.h before Ksproxy.h.

Library: Use Strmiids.lib.
