NAME
       explain_signalfd_or_die - create signalable file descriptor and report errors

SYNOPSIS
       #include <libexplain/signalfd.h>
       int explain_signalfd_or_die(int fildes, const sigset_t *mask, int flags);
       int explain_signalfd_on_error(int fildes, const sigset_t *mask, int flags);

DESCRIPTION
       The  explain_signalfd_or_die  function  is  used  to call the signalfd(2) system call. On failure an explanation will be printed to stderr,
       obtained from the explain_signalfd(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_signalfd_on_error function is used to call the signalfd(2) system call. On failure an explanation will be  printed  to  stderr,
       obtained from the explain_signalfd(3) function, but still returns to the caller.

       fildes  The fildes, exactly as to be passed to the signalfd(2) system call.

       mask    The mask, exactly as to be passed to the signalfd(2) system call.

       flags   The flags, exactly as to be passed to the signalfd(2) system call.

RETURN VALUE
       The  explain_signalfd_or_die  function only returns on success, see signalfd(2) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_signalfd_on_error function always returns the value return by the wrapped signalfd(2) system call.

EXAMPLE
       The explain_signalfd_or_die function is intended to be used in a fashion similar to the following example:
	      int result = explain_signalfd_or_die(fildes, mask, flags);

SEE ALSO
       signalfd(2)
	       create a file descriptor for accepting signals

       explain_signalfd(3)
	       explain signalfd(2) errors

       exit(2) terminate the calling process
