NAME

       explain_pipe2_or_die - create pipe and report errors

SYNOPSIS

       #include <libexplain/pipe2.h>
       void explain_pipe2_or_die(int *fildes, int flags);
       int explain_pipe2_on_error(int *fildes, int flags);

DESCRIPTION

       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.

RETURN VALUE

       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.

EXAMPLE

       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);
