|Microsoft DirectX 9.0|
The CheckSizes method checks allocator properties against the current media type.
HRESULT CheckSizes( ALLOCATOR_PROPERTIES *pRequest );
Pointer to an ALLOCATOR_PROPERTIES structure that describes the requested allocator properties.
Returns an HRESULT value. Possible values include the following.
|S_OK||The requested properties are compatible with the media type.|
|E_INVALIDARG||The requested properties are not compatible with the media type.|
|VFW_E_NOT_CONNECTED||The owning pin is not connected.|
When the method returns, if the return value is S_OK, the cbBuffer member of pRequest contains the actual buffer size. This might be larger than the requested size, but will never be smaller.
