On failure an explanation will be printed to stderr, ob- tained from the explain_fchownat(3) function, and then the process ter- minates by calling exit(EXIT_FAILURE). The explain_fchownat_on_error function is used to call the fchownat(2) system call. On failure an explanation will be printed to stderr, ob- tained from the explain_fchownat(3) function, but still returns to the caller. dirfd The dirfd, exactly as to be passed to the fchownat(2) system call. pathname The pathname, exactly as to be passed to the fchownat(2) system call. owner The owner, exactly as to be passed to the fchownat(2) system call. group The group, exactly as to be passed to the fchownat(2) system call. flags The flags, exactly as to be passed to the fchownat(2) system call.
