int libmem_lock | ( | uint8_t * | start,
|  | size_t | size
| ) |
  | Lock a block of memory using a LIBMEM driver. Parameters:
  | start | A pointer to the start address of the memory range to lock.
  | size | The size of the memory range to lock in bytes.
Returns: The LIBMEM status result. This function locates the LIBMEM driver for the address pointed to by start and then calls the LIBMEM driver's lock function. Example:
        int res;

        res = libmem_lock((uint8_t *)0x10000000, 1024);

        if (res == LIBMEM_STATUS_SUCCESS)
          printf("libmem_lock : success\n");
        else
          printf("libmem_lock : failed (%d)\n", res);
