eryksun added the comment:
This also affects SEH-related exceptions raised by ctypes. For example, VC++
uses exception code 0xE06D7363 (i.e. b'\xe0msc'), so unhandled VC++ exceptions
leak into Python like this:
>>> ctypes.windll.kernel32.RaiseException(0xe06d7363, 0, 0, None)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [WinError -529697949] Windows Error 0x%X
The ctypes SEH handler defaults to calling PyErr_SetFromWindowsErr(code). Since
this isn't actually a Windows error code, Win32 FormatMessageW fails. Then
Python uses the following default: PyUnicode_FromFormat("Windows Error 0x%X",
err).
Normally (i.e. not under Wine) the OP's error number formats correctly:
>>> ctypes.windll.kernel32.RaiseException(10054, 0, 0, None)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ConnectionResetError: [WinError 10054] An existing connection was forcibly
closed by the remote host
