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);
