If you use the same workflow as you do currently, it won't: 1. Feed input to your custom stdin object, which will buffer the code. 2. Call PyRun_IteractiveOne - it will read from your object, which will return the buffer contents. 3. The result is somehow handled by custom stdout and stderr objects. > > Maybe I could use a file-like object to communicate the results to my > c++ application and use the code > module to execute code only when the c++ application needs it. > -- http://mail.python.org/mailman/listinfo/python-list
