Hi,
looks good to me. I was thinking about getting rid of that ifdef,
but I'm not sure it's worth the trouble for such trivial testcase.
Small nits (related to original code):
- no need for brackets for single statement
- it would be helpful to see the errno in case of failure:
tst_resm(TFAIL | TTERRNO, "failed with unexpected errno");
- "malloc failed" flags should be TFAIL | TERRNO
- tst_tmpdir()/tst_rmdir() is not needed
- unnecessary comments can be removed
Regards,
Jan
