explain_timerfd_create_or_dLibrary Functions Mexplain_timerfd_create_or_die(3)

NAME
       explain_timerfd_create_or_die  -	 create	file descriptor	timers and re-
       port 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)	 func-
       tion, 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) func-
       tion, 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 explana-
       tion 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);

	       timers that notify via file descriptors

       explain_timerfd_create(3)
