NAME
       explain_timerfd_create_or_die - create file descriptor timers and report errors

SYNOPSIS
       #include <libexplain/timerfd_create.h>
       int explain_timerfd_create_or_die(int clockid, int flags);
       int explain_timerfd_create_on_error(int clockid, int flags);

DESCRIPTION
       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.

       clockid The clockid, exactly as to be passed to the timerfd_create(2) system call.

       flags   The flags, exactly as to be passed to the timerfd_create(2) system call.

RETURN VALUE
       The explain_timerfd_create_or_die function only returns on success, see timerfd_create(2)
       for more information. On failure, prints an explanation and exits, it does not return.

       The explain_timerfd_create_on_error function always returns the value return by the
       wrapped timerfd_create(2) system call.

EXAMPLE
       The explain_timerfd_create_or_die function is intended to be used in a fashion similar to
       the following example:
              int result = explain_timerfd_create_or_die(clockid, flags);
