Functions
uint64_t	space_init (space_t *space, uintptr_t startAddress, uintptr_t endAddress, space_flags_t flags)
	Initializes a virtual address space.
void	space_deinit (space_t *space)
	Deinitializes a virtual address space.
void	space_load (space_t *space)
	Loads a virtual address space.
uint64_t	space_pin (space_t *space, const void *address, uint64_t length, stack_pointer_t *userStack)
