The ctypes.WinError function returns:
OSError(None, descr, None, code)
However OSError does not appear to allow None as a first argument, and converts it to 22 which is the EINVAL "Invalid Argument" error. This is rather confusing as there was no invalid argument errors in the code.
I think the behaviour for one of WinError and OSError should be modified so that the handling of errno is more compatible.

No, OSError.errno is converted from the Windows error code. There is a translation map (see PC/errmap.h, built with the _dosmaperr() function) and the default value is EINVAL. It's working as intended. What was the winerror code? do you think it should be mapped to another errno? |

Ok, my bad, I was creating my own OSErrors so I was just testing it out. I just found the default to be rather confusing as I thought None would not be mapped to anything. |

> the default value is EINVAL. Should that be specified in the docs? Currently it states that "[t]he errno attribute is then an approximate translation, in POSIX terms, of that native error code". https://docs.python.org/3/library/exceptions.html#OSError |
