[C++-SIG] Controlling python execution from C

[Marcelo Kallmann]

Hello,

Looking at the manuals, I saw that the function Py_NewInterpreter(), "simulates"
the creation of a new thread, so that different scripts would be interpreted
"pratically" in paralell by interpreting some bytecodes of each one from time to
time. There is even a method to say how many bytecodes to interpret in one
script (default=10) before changing to interpret the next script.

I tryed to test this feature from C calls, by playing with thread states,
interpreter states, run_string, etc, but with no success...

What I would like to do is to have n scripts ( char *script[n]; ), and be able
to run them in the same application loop, having something like :

while ( true )
{  for ( int i=0; i<n; i++ )
    { restore_python_thread_state ( i ); // would call python functions to
restore internal states, etc.
       run_some_bytecodes_of_python_script ( script[i]  );  // would not block
my loop, would not run all the script !
    }
  ....
}

So, first of all, my question is : Is this possible to do ?
If so, can someone explain me, or send me some example code please.

Thank you all,

Marcelo K.
