Author: thomas.heller Date: Mon Apr 30 18:04:57 2007 New Revision: 55027 Modified: python/trunk/Modules/_ctypes/cfield.c Log: When accessing the .value attribute of a c_wchar_p instance, and the instance does not point to a valid wchar_t zero-terminated string, raise a ValueError. c_char_p does this already. The ValueError message now contains the correct pointer address. Will backport to release25-maint.
