Conformance Status

• Assertion 1 is partially tested in the OPTS. A new testcase will be written to test setting of sched parameter in another thread.
  
• Assertion 2 is not tested. A new testcase will be written with a wrong priority parameter. Anyway, it is not required that the function returns an error -- so the test might not work.
  
• Assertion 3 is not tested. A new testcase will be written.
