Some base utilities sometimes close files that they open for their purposes without checking the error code of close(2). Is this considered to be ok, because it's just a close call and we are done with that file descriptor, or is it considered to be more appropriate to check close's error code? Maybe there is some policy that covers this? IMO, every system call's return value should be checked, just in case. Yuri
