We get file matches when their attributes match and we can obtain a valid 8.3 file name. This last condition is of upmost importance. We cannot reliably use GetShortPathName() on the filename returned by FindFirstFile()/FindNextFile() because the result is uncertain (one either needs to build a full path before calling the function just to get the final short path form, or change the current working directory to the one where the search is being made, etc.) The Find*file() functions return anyway the short file. name (in the cAlternateFileName member) if the file does have such 8.3 filename and its real name (in cFileName) is longer. Otherwise, cFileName could already be *THE* short filename because it has the correct format for it. Check this latter case with RtlIsNameLegalDOS8Dot3() and use it if so. Otherwise this means the file has a long filename that cannot be converted to short filename format (because e.g. it is in a volume where short filenames are unavailable), and we skip such files: they wouldn't be accessible from DOS anyways. - Doxygen-document demFileFindFirst(), demFileFindNext() and associated flags and structures. Update their annotations. This fixes TurboC 2.x installation.
