CPosPassThru::ForceRefresh (Compact 2013)
3/26/2014
Releases any cached interfaces on the upstream pin.
Syntax
HRESULT ForceRefresh( );
Parameters
None.
Return Value
Returns S_OK.
Remarks
For efficiency, the CPosPassThru class can cache the IMediaPosition interface of the connected upstream output pin.
This method releases any cached interface pointers and forces them to be obtained again through QueryInterface if needed.
Presently, this class does not cache the upstream IMediaPosition so this member function is not necessary.
