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);
