15: errno.ENOTBLK,
^^^^^^^^^^^^^
AttributeError: module 'errno' has no attribute 'ENOTBLK'. Did you mean: 'ENOTSOCK'?
Additional Information
Windows doesn’t use the same device classification system as Unix-like OSes. It doesn't differentiate between block and character devices in the same way, so the concept of a "block device" doesn’t map directly. Because of that, Windows’ version of the errno list omits ENOTBLK.
Likely this list needs to be built taking the platform into account, and/or wrapped in appropriate error handling.
if platform.system() != "Windows":
MP_ERRNO_TABLE[15] = errno.ENOTBLK
