Hi! In callproc.c from trunk is a function called SetException(), which calls FormatError() only to discard the contents. Can anyone enlighten me to the reasons thereof? Is it just to check if the errorcode is registered in the stringtables? The reason I ask is the CE port. The FormatMessage API exists there (or, rather, the FormatMessageW API), but the tables containing the error messages are optional for the OS and for space reasons many vendors chose not to include them. That means that the function there regularly fails to retrieve the requested string. My first approach was to fall back to simply providing a sting with a numeric representation of the errorcode, but that would change the meaning of above function, because then it could never fails. My second approach was to enhance PyErr_SetFromWindowsErr() to handle the additional error codes that are checked in SetException(). However, those require more context than just the error code, they use the EXCEPTION_RECORD passed to SetException() for that. My third approach would be to filter out the special error codes first and delegate all others to PyErr_SetFromWindowsErr(). The latter already handles the lack of a string for the code by formatting it numerically. This would also improve consistency, since the two functions use different ways to format unrecognised errors numerically. This approach would change where and how a completely unrecognised error code is formatted, but would otherwise be pretty equivalent. Suggestions?
