CTransInPlaceInputPin::NotifyAllocator (Windows CE 5.0)
Receives notification of which allocator will be used by the connected output pin.
HRESULT NotifyAllocator(IMemAllocator* pAllocator,BOOLbReadOnly);
Parameters
pAllocator
Pointer to the IMemAllocator object to use.This might or might not be the same CTransInPlaceInputPin object that the input pin provided in the CTransInPlaceInputPin::GetAllocator member function (the output pin could provide its own allocator).
bReadOnly
Flag to indicate if the samples from this allocator are read-only.
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.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
