Detailed Description

helper class for attaching the current thread to the python runtime.

Attaching is done creating a new threadstate for the given interpreter and acquiring the global interpreter lock.

Usage:

... don't use python here { PyThreadAttach guard( PyInterpreterState_Head() ); { ... do whatever python code you want { PyThreadDetach antiguard; ... don't use python here } ... do whatever python code you want } } ... don't use python here

Note: The additional scope brackets after the PyThreadAttach are needed, e.g. when you would leave them away, dtors of potential pyrefs may be called after the thread has detached again.
