Function Documentation

errval_t vspace_map_anon_aligned	(	void **	retaddr,
		struct memobj **	ret_memobj,
		struct vregion **	ret_vregion,
		size_t	size,
		size_t *	retsize,
		vregion_flags_t	flags,
		size_t	alignment
	)

Wrapper for creating and mapping a memory object of type anonymous.

The memory object and vregion are returned so the user can call fill and pagefault on it to create actual mappings.

		struct memobj **	ret_memobj,
		struct vregion **	ret_vregion,

		vregion_flags_t	flags
	)

Wrapper for creating and mapping a memory object of type anonymous.

The memory object and vregion are returned so the user can call fill and pagefault on it to create actual mappings.

		struct memobj **	ret_memobj
	)

Wrapper to create and map an anonymous memory object at a fixed address.
