DESCRIPTION

15       The explain_puts_or_die function is used to  call  the  puts(3)  system
16       call.  On  failure  an  explanation will be printed to stderr, obtained
17       from the explain_puts(3) function, and then the process  terminates  by
18       calling exit(EXIT_FAILURE).
19
20       The  explain_puts_on_error  function is used to call the puts(3) system
21       call. On failure an explanation will be  printed  to  stderr,  obtained
22       from the explain_puts(3) function, but still returns to the caller.
