The return value of pthread_getattr_np is correct, I double checked it. But the values of element in attr structure are not correct, like stack_addr and stack_size.

Yes, I know this. I just do not know how to do this. The implementation of pthread_getattr_np of 4.11 and 4.12 are different, I just do not know where do I start from...

It would be good to check the expected values with test assertions.
