IKsPropertySet::QuerySupported method (ksproxy.h)
The QuerySupported method determines whether a KS object supports a property set and the type of that support.
Syntax
HRESULT QuerySupported(
[in] REFGUID PropSet,
[in] ULONG Id,
[out] ULONG *TypeSupport
);
Parameters
[in] PropSet
GUID that identifies the property set.
[in] Id
Identifier of the property within the property set.
[out] TypeSupport
Pointer to a variable that receives a bitmask enumerating the flags that indicate the support that the underlying driver provides. A driver can support a bitwise OR combination of the following flags:
| Value | Description |
|---|---|
| KSPROPERTY_SUPPORT_GET | Supports retrieving a property. Use the IKsPropertySet::Get method to retrieve the property. |
| KSPROPERTY_SUPPORT_SET | Supports setting a property. Use the IKsPropertySet::Set method to set the property. |
Return value
Returns NOERROR if successful; otherwise, returns one of the following error codes:
| Return code | Description |
|---|---|
| E_NOTIMPL | Property set is not supported. |
| E_PROP_ID_UNSUPPORTED | Property identifier (Id) is not supported for the specified property set. |
| E_PROP_SET_UNSUPPORTED | Property set is not supported. |
Remarks
KS objects include, for example, KS filters, KS pins, and KS clocks.
Warning
Header files ksproxy.h and dsound.h define similar but incompatible versions of the IKsPropertySet interface. Applications that require the KS proxy module should use the version defined in ksproxy.h. If an application must include both ksproxy.h and dsound.h, whichever header file the compiler scans first is the one whose definition of IKsPropertySet is used by the compiler.
Requirements
| Requirement | Value |
|---|---|
| Target Platform | Desktop |
| Header | ksproxy.h (include Ksproxy.h, Dsound.h) |
