I have a problem with embedding Python into a C extension in Windows Vista. I have implemented a timer routine in C as an extension, which I can import into Python 2.6.5 and run. Each timer interval, the extension calls a C CALLBACK function. I want to be able to have this CALLBACK function call a Python function, so that I can write the timer handler in Python.
I can write Python functions and call them from a C extension function with no trouble in all cases EXCEPT when the function that calls the Python code is the timer's CALLBACK function. That is, if I call PyRun_SimpleString or PyRun_SimpleFile, or PyImport_ImportModule, or basically any Python-y function in the CALLBACK function, Python crashes and I get a window saying "Python has stopped working. Windows is searching for a solution to the problem." The Python code runs fine if I call it from a function in the extension that is not the CALLBACK function. And regular C code runs in the CALLBACK function properly. It only crashes if I try to run the Python code from the timer CALLBACK function (or any C function I call from the CALLBACK function). Does anybody know how to fix this? Is there a workaround of some sort? -- http://mail.python.org/mailman/listinfo/python-list
