		size_t	chunk_size
	)

Initialize.

Parameters

memobj	The memory object
size	Size of the memory region
flags	Memory object specific flags

This object handles multiple frames. The frames are mapped in on demand.

errval_t memobj_create_numa	(	struct memobj_numa *	mo_numa,
		size_t	size,
		memobj_flags_t	flags,

		size_t	size,
		memobj_flags_t	flags,
		struct capref	frame,
		size_t	chunk_size
	)

Initialize a memory object of type one frame.

Parameters
