CBaseAllocator::Decommit
| Microsoft DirectShow 9.0 |
CBaseAllocator::Decommit
The Decommit method decommits the allocator. This method implements the IMemAllocator::Decommit method.
Syntax
HRESULT Decommit(void);
Return Value
Returns S_OK.
Remarks
After this method is called, calls to the CBaseAllocator::GetBuffer method will fail. As samples are released, they get returned to the free list. When the last sample is returned, the allocator calls the CBaseAllocator::Free method, which releases the allocated memory. (In the base class, Free is a pure virtual method.)
In addition, this method releases any threads that are blocked on GetBuffer calls. The calls to GetBuffer fail.
Requirements
** Header:** Declared in Amfilter.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
