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);
