CBaseAllocator::Free

  • 项目

Called to decommit the memory when the last buffer is freed.

virtual void Free(void) PURE;

Parameters

None.

Return Values

None.

Remarks

This member function must be implemented in the derived class. It is called from CBaseAllocator::ReleaseBuffer when a decommit is pending and the allocator has put its last buffer on the free list. It is also called from CBaseAllocator::Decommit.

The CMemAllocator::Free member function is an example of how this can be implemented in the derived class. In this case, it simply returns, because the CMemAllocator class releases memory from its destructor.

This member function is protected.

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.
