I admit I don't know enough to say how the lpt1 issue should be handled. Is there any Win32 call I can make that will help me avoid accidentally opening these magic files? Say, if I call open with O_CREAT | O_EXCL? Unfortunately, I can find very little information on how one should handle this issue.
Thanks to a suggestion from Bulat to use c_open, I was able to test O_WRONLY | O_CREAT | O_EXCL on Windows. In fact, Windows does allow files like "nul" to be opened (as many times as you like) with these flags, which I find dismaying. So I still don't know the proper way to handle them.
You can open the file and test the file type with GetFileType. If it's type FILE_TYPE_CHAR then it's probably not what you wanted. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/g... Duncan
