[issue12437] _ctypes.dlopen does not include errno in OSError

[Santoso Wijaya]

Santoso Wijaya <santoso.wijaya at gmail.com> added the comment:

>From what I gather from the code, when dlopen fails in POSIX platforms, ctypes raises an PyExc_OSError instantiated with a simple string (via PyErr_SetString()). I suppose this could be changed to raise a more complex tuple, instead (like its WindowsError equivalent when LoadLibrary fails in Windows platforms), but that might break existing code that relies on this behavior. 3.3 only?
