CBaseInputPin::GetAllocator
| Microsoft DirectShow 9.0 |
CBaseInputPin::GetAllocator
The GetAllocator method retrieves the memory allocator proposed by this pin. This method implements the IMemInputPin::GetAllocator method.
Syntax
HRESULT GetAllocator(
IMemAllocator **ppAllocator
);
Parameters
ppAllocator
Address of a variable that receives a pointer to the allocator's IMemAllocator interface.
Return Value
Returns S_OK if successful, or an error code from the CoCreateInstance function.
Remarks
This method creates a CMemAllocator object. Override this method if your filter uses an allocator from a downstream pin, or a custom allocator.
If the method succeeds, the IMemAllocator interface has an outstanding reference count. Be sure to release it when you are done.
Requirements
** Header:** Declared in Amfilter.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
