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);
