SurfaceHeap Constructor (Windows Embedded CE 6.0)
1/6/2010
When the SurfaceHeap class is created, the constructor allocates a heap starting from an address that you specify. Initially, drivers should create a SurfaceHeap object, giving it the total memory size available for graphics. Thereafter, that SurfaceHeap object can be used to request smaller blocks of data.
SurfaceHeap(
DWORD size,
ADDRESS base,
SurfaceHeap* pNext,
SurfaceHeap* pPrev
);
Parameters
- size
The size, in bytes, for the new heap. When you first create your heap, this value should be the total size of available memory.
- base
The starting address for the heap.
- pNext
The next heap in the list. When the heap is first created, this parameter should be set to NULL.
- pPrev
The previous heap in the list. When the heap is first created, this parameter should be set to NULL.
Return Values
None.
Remarks
When a SurfaceHeap object is destroyed, memory that has been allocated for it, and all of its subheaps, is marked for reuse. If the top-level heap is destroyed, all memory is deallocated.
