-/* Specify the reaction to an EPIPE error during the closing of stdout:
-     - If ignore = true, it shall be ignored.
-     - If ignore = false, it shall evoke a diagnostic, along with a nonzero
-       exit status.
-   The default is ignore = false.
-
-   This setting matters only if the SIGPIPE signal is ignored (i.e. its
-   handler set to SIG_IGN) or blocked.  Only particular programs need to
-   temporarily ignore SIGPIPE.  If SIGPIPE is ignored or blocked because
-   it was ignored or blocked in the parent process when it created the
-   child process, it usually is a bug in the parent process: It is bad
-   practice to have SIGPIPE ignored or blocked while creating a child
-   process.
-
-   EPIPE occurs when writing to a pipe or socket that has no readers now,
-   when SIGPIPE is ignored or blocked.
-
-   The ignore = false setting is suitable for a scenario where it is normally
-   guaranteed that the pipe writer terminates before the pipe reader.  In
-   this case, an EPIPE is an indication of a premature termination of the
-   pipe reader and should lead to a diagnostic and a nonzero exit status.
-
-   The ignore = true setting is suitable for a scenario where you don't know
-   ahead of time whether the pipe writer or the pipe reader will terminate
-   first.  In this case, an EPIPE is an indication that the pipe writer can
-   stop doing useless write() calls; this is what close_stdout does anyway.
-   EPIPE is part of the normal pipe/socket shutdown protocol in this case,
-   and should not lead to a diagnostic message.  */

-/* Close standard output.  On error, issue a diagnostic and _exit
-   with status 'exit_failure'.
-
-   Also close standard error.  On error, _exit with status 'exit_failure'.
-
-   Since close_stdout is commonly registered via 'atexit', POSIX
-   and the C standard both say that it should not call 'exit',
-   because the behavior is undefined if 'exit' is called more than
-   once.  So it calls '_exit' instead of 'exit'.  If close_stdout
-   is registered via atexit before other functions are registered,
-   the other functions can act before this _exit is invoked.
-
-   Applications that use close_stdout should flush any streams
-   other than stdout and stderr before exiting, since the call to
-   _exit will bypass other buffer flushing.  Applications should
-   be flushing and closing other streams anyway, to check for I/O
-   errors.  Also, applications should not use tmpfile, since _exit
-   can bypass the removal of these files.
-
-   It's important to detect such failures and exit nonzero because many
-   tools (most notably 'make' and other build-management systems) depend
-   on being able to detect failure in other tools via their exit status.  */
