不从默认堆分派内存单元

通常，内存单元的分配都是从当前进程堆，但有些时候不可能这样，特别是当内存单元特别大时。通过以下说明可以创建一个新堆来分配新的内存单元：

CODE:

//Try to create a heap in a local chunk. The minimum length of the heap is 10M and the maximum length is 20M

RHeap *pChunkHeap = UserHeap::ChunkHeap(NULL, 10000*1024, 20000*1024);

if (RHeap)

{

void *mallocBuffer = NULL;

TInt size = 8000*1024; //Try to allocate a 8M memory cell

mallocBuffer = pChunkHeap->Alloc(size);

if (mallocBuffer )

{

//... Use this memory cell ...

}

}
