CTransInPlaceInputPin::NotifyAllocator

Receives notification of which allocator will be used by the connected output pin.

HRESULT NotifyAllocator(
  IMemAllocator* pAllocator,
  BOOL bReadOnly 
);

Parameters

Return Values

Returns NOERROR if successful. Returns E_POINTER if the pointer is invalid. Otherwise, returns an error due to calling CTransInPlaceOutputPin::ReceiveAllocator.

Remarks

This member function overrides the CBaseInputPin::NotifyAllocator member function and implements the IMemInputPin::NotifyAllocator method. This member function remembers the allocator and passes it to the output pin because they both must share the same allocator.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
