CTransInPlaceInputPin::NotifyAllocator (Windows Embedded CE 6.0)
1/6/2010
Receives notification of which allocator will be used by the connected output pin.
Syntax
HRESULT NotifyAllocator(
IMemAllocator* pAllocator,
BOOL bReadOnly
);
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 Value
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.
