That'd be more sure. Where are you looking at? passive translators have
at best their output sent to the mach console, *not* the stdout of where
you run programs using them (even if that's what triggered their start).
And you have to flush the output stream, even if it's stderr.

S_foobar () {} function definition is server code and foobar() call is
client code. Just like the former is the implementation of a function,
and the latter is the caller of the function.
