typedef int(* libmem_driver_inrange_fn_t)(libmem_driver_handle_t *h, const uint8_t *dest)
  | A function pointer to a LIBMEM driver's inrange extended function. Parameters:
  | h | A pointer to the handle of the LIBMEM driver.
  | dest | A pointer to then memory location being tested.
Returns: The LIBMEM status result. The driver's inrange function is an optional extended function. It has been provided to allow the driver to indicate if it handles a more complex memory range than the single range described by the start and size libmem_driver_handle_t fields, for example if the memory has been aliased over a number of memory ranges. The function should return non-zero if the address pointed to by dest is handled by the driver.
