Dear developers, i am trying to register a Python function as error handler callback using ctypes in libgis. I use this code in the temporal framework:
{{{ def error_handler(data): pass CALLBACK = CFUNCTYPE(None, c_void_p) CALLBACK.restype = None CALLBACK.argtypes = c_void_p cerror_handler = CALLBACK(error_handler) libgis.G_add_error_handler(cerror_handler, POINTER(None)) }}} Unfortunately i get this error: {{{ Traceback (most recent call last): File "/usr/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap self.run() File "/usr/lib/python2.7/multiprocessing/process.py", line 114, in run self._target(*self._args, **self._kwargs) File "/home/soeren/src/grass7.1/grass_trunk/dist.x86_64-unknown-linux-gnu/etc/python/grass/temporal/c_libraries_interface.py", line 759, in c_library_server libgis.G_add_error_handler(cerror_handler, POINTER(None)) ArgumentError: argument 1: <type 'exceptions.TypeError'>: expected CFunctionType instance instead of CFunctionType }}} Does anyone know what the correct way is to register a Python function as error handler in libgis? Any help is highly welcome. Best regards Soeren _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
