IKsPropertySet::QuerySupported

Microsoft DirectShow 9.0

  DWORD dwPropID,
  DWORD *pTypeSupport
);

Parameters

guidPropSet

[in] Property set GUID.

dwPropID

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

pTypeSupport

[out] Pointer to a value in which to store flags indicating the support provided by the driver. Supported flags include the following.

Value	Description
KSPROPERTY_SUPPORT_GET	You can retrieve the property by calling the IKsPropertySet::Get method.
KSPROPERTY_SUPPORT_SET	You can change the property by calling IKsPropertySet::Set.

Return Values

Returns an HRESULT value. Possible values include the following.

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.
