it works!
could i cache maindict pointer in a global var or am i condemned to
call
PyObject* mainmod = PyImport_AddModule("__main__");
assert(mainmod);
PyObject* maindict = PyModule_GetDict(mainmod);
assert(maindict);
every time i want to PyRun_String?
i call Py_Finalize only atexit.
i also found boost library docs of some help:
http://service-spi.web.cern.ch/service-spi/external/Boost/1.30.0/rh73_gcc32/libs/python/doc/tutorial/doc/using_the_interpreter.html
btw what kind of object is returned in case i use Py_file_input
in PyRun_String?
