I found out that there is a test in 4.12-master about
pthread_getattr_np, so I compiled that one and ran it.
The result shows that this function works well, like this
*************************************************************************
*** BEGIN OF TEST PSXGETATTRNP 1 ***
Init - pthread_getattr_np - attr NULL - EINVAL
Init - pthread_getattr_np - invalid id - ESRCH
Init - pthread_attr_init

Init - pthread_attr_setschedparam to minimum priority + 2
Init - pthread_attr_getstack
Init - pthread_attr_setstack double the stacksize
Init - pthread_attr_getguardsize
Init - pthread_attr_setguardsize double the guardsizecreate
Init - Lower pri
Init - raise priority to max
Init - pthread_ority
Thread - pthread_getattr_np - Verify value
Thread - pthread_setschedparam: Setting highest priority SCHED_FIFO
Thread - Detach

Thread - Verify SCHED_FIFO policy
Thread - Verify max priority

*** END OF

But, this test just checks the return value, not the value of elements
in pthread_attr_t structure. When I tried to print out these values,
the same result as before appeared, all 0...
It would be good to check the expected values with test assertions.
So, how can I modify the source code in rtems to let this function
work? Thanks a lot.
You have to edit:
