[LTP] [PATCH v4] timers/timer_create0{2, 3, 4}: Ported to new library
Christian Amann
camann@suse.com
Fri Jul 19 13:37:21 CEST 2019
Merged timer_create0{2,3} into one test, cleaned up and ported the
tests to the new library. Also added missing clocks and made
sure that optional clocks are tested if they are not available and
fail at runtime.
timer_create04: Added error handling test for wrong contents of the
sigevent structure.
Signed-off-by: Christian Amann <camann@suse.com>
---
Notes:
Sorry for removing the CLEANUP() makro in the last version.
I wanted to test something without it and must have let it out,
accidently.
In this iteration I added an EINVAL test for wrong contents of
the sigevent structure. The other EINVAL test for a wrong clock
ID didn't really fit into this test case without making it too
hacky.
