int explain_timerfd_create_on_error(int clockid, int flags);
Overview
The explain_timerfd_create_or_die function is used to call the timerfd_create(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_timerfd_create(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_timerfd_create_on_error function is used to call the timerfd_create(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_timerfd_create(3) function, but still returns to the caller.
