You could use a PyBuffer_FromReadWriteMemory() or a PyString_FromStringAndSize() with Python 2.4. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Oct 19 2012) >>> Python Projects, Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope/Plone.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ 2012-09-27: Released eGenix PyRun 1.1.0 ... http://egenix.com/go35 2012-09-26: Released mxODBC.Connect 2.0.1 ... http://egenix.com/go34 2012-09-25: Released mxODBC 3.2.1 ... http://egenix.com/go33 2012-10-23: Python Meeting Duesseldorf ... 4 days to go eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.

Equivalent of PyByteArray_FromStringAndSize in python2.4
by endeavor john Oct. 19, 2012

Oct. 19, 2012

Hello Team, While cross-compiling XBMC Apllication.The code is generated using Java. I am getting an error :PyByteArray_FromStringAndSize.is undefined, i understand that this api is defined in python2.6. But we are supposed to compile this with python-2.4 libraries. Can you please let us know what is the equivalent API in python 2.4.This is the Code which using the "PyByteArray_FromStringAndSize" API. static PyObject* xbmc_XBMCAddon_xbmc_RenderCapture_getImage(PyObject* self, PyObject *args, PyObject *kwds) { RenderCapture* rc = ((RenderCapture*)retrieveApiInstance((PyObject*)self,&PyXBMCAddon_xbmc_RenderCapture_Type,"getImage","XBMCAddon::xbmc::RenderCapture")); if (rc->GetUserState() != CAPTURESTATE_DONE) { PyErr_SetString(PyExc_SystemError, "illegal user state"); return NULL; } ssize_t size = rc->getWidth() * rc->getHeight() * 4; return PyByteArray_FromStringAndSize((const char *)rc->GetPixels(), size); } Thanks, John

Triggering a KeyboardInterrupt in a PyObject_CallObject
by Enrico Granata Oct. 11, 2012

Oct. 11, 2012

Hi list. I have a situation where I make a PyObject_CallObject call on one thread, and then I watch for keyboard input on a separate thread. When the user hits CTRL-C, this second thread will see it and needs to make it so that the callable being run on the first thread gets "stopped" with a KeyboardInterrupt exception I tried calling Py_AddPendingCall() on the second thread, and passing it a pointer to a function foo. My first attempt was to make foo call PyErr_SetInterrupt() and PyErr_CheckSignals(). Since this did not work, I rewrote foo to explicitly set the KeyboardInterrupt exception with PyErr_SetString() and returning -1 This worked in the sense that I saw the KeyboardInterrupt come out on screen as a traceback, but it did not stop the function from running. Am I doing something wrong? Is there even a way to raise an exception "inside" a PyObject_CallObject without the callee doing anything? It would be much preferable that the called python object did not have to do anything in order to be interruptible, but I would be willing to compromise on some simple "make me interruptible" pattern, provided it really is simple. Thanks for any help. Enrico Granata ✉ egranata@.com ✆ (408) 972-7683
