Trying to map as many error codes that closely match as possible for general usage without the #ifdefs (beyond what is used for the mappings), currently trying to identify the equivalent of EBADE, so far I've tried just doing a search for EXCHANGE in the win32 error codes with nothing to show for it, so I thought about trying different search terms but to do that I need to clearly understand what linux views as an exchange for this code to be returned, nothing I've found on the net so far actually explains this, anyone here able to?
