nn::fnd::ExpHeapTemplate::Create Member Function

static ExpHeapTemplate * Create(
     HeapBase * parent,
     void * addr,
     size_t size,
     bit32 option = 0,
     bit32 placement = HEAP_INFOPLACEMENT_HEAD
);

	Name	Description
in	parent	Specifies the parent heap whose region contains addr.
in	addr	The starting address of the memory block to be allocated to the heap.
in	size	The size of the memory block to be allocated to the heap.
in	option	Specifies options.
in	placement	Specifies the location where the management region (ExpHeap object) is located.

Creates an expanded heap within a parent heap.

Heaps that are created with this function must be destroyed using HeapBase::Destroy.

The actual ExpHeap object is created within the region defined by the values specified for the addr and size arguments. This means that the actual size allocated to the heap is the size of the specified region minus sizeof(ExpHeap).

Use the placement argument to specify where the ExpHeap object is placed. If you specify HEAP_INFOPLACEMENT_HEAD for placement, the actual ExpHeap object is placed at the start of the region (in other words, the region that starts at addr and ends at addr+sizeof(ExpHeap). If you specify HEAP_INFOPLACEMENT_TAIL for placement, the actual ExpHeap object is placed at the end of the region (in other words, the region that starts at addr+size-sizeof(ExpHeap) and ends at addr+size.
