                                                                                         explain_pipe2_or_die(3)

       The  explain_pipe2_or_die  function  is  used to call the pipe2(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_pipe2(3) function, and then the  process  terminates
       by calling exit(EXIT_FAILURE).

       The  explain_pipe2_on_error  function is used to call the pipe2(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_pipe2(3) function, but still returns to the caller.

       fildes  The fildes, exactly as to be passed to the pipe2(2) system call.

       flags   The flags, exactly as to be passed to the pipe2(2) system call.

       The explain_pipe2_or_die function is intended to be used in a fashion similar to the following example:
              explain_pipe2_or_die(fildes, flags);

       explain_pipe2_or_die - create pipe and report errors

       The explain_pipe2_or_die function only returns on success, see pipe2(2) for more information. On failure,
       prints an explanation and exits, it does not return.

       The explain_pipe2_on_error function always returns the value return by the wrapped pipe2(2) system call.

pipe2(2)
               create pipe

       explain_pipe2(3)
               explain pipe2(2) errors

       exit(2) terminate the calling process
