/* Fun Facts for Inquiring Minds Episode 257.
*
* Hi Kids! Were you aware that the MSDN entry for FindFirstFile()
* contains this pithy statement?
*
* An attempt to open a search with a trailing backlash always fails.
*
* So what does this mean for all of you kids out there in Internet
* Land? Well it means that starting a search for D:\wml using
* FindFirstFile() will succeed, but a search using D:\wml\
* will fail horribly. Don't believe me? Go try it yourself.
* I'll wait.
*
* ...
*
* So did you see it? FindFirstFile() on D:\wml\ returned
* INVALID_HANDLE_VALUE! Wow, that's a surprise.
*
* So what do we do about it? Well the most obvious fix would be
* to just zap the trailing backslash with a null character. That
* turns something like D:\wml\ into D:\wml, which we already know
* works. However, ... you might want to try that trick again with
* a directory name like D:\. I'll wait until you do.
*
* ...
*
* So ... You got INVALID_HANDLE_VALUE, didn't you. Well, the zap
* trick turned D:\ into D:, but plain driver names like A:, B:,
* C:, D:, etc. are not accepted by FindFirstFile(), no way, no how.
*
* So what do we do? As it happens, Microsoft does have some more
* verbiage about this:
*
* As stated previously, you cannot use a trailing backslash (\) in
* the lpFileName input string for FindFirstFile, therefore it may
* not be obvious how to search root directories. If you want to see
* files or get the attributes of a root directory, the following
* options would apply:
*
* To examine files in a root directory, you can use "C:\*" and
* step through the directory by using FindNextFile.
*
* To get the attributes of a root directory, use the
* GetFileAttributes function.
*
* In that case, the fix is to look and see if there is a trailing
* backslash and append a '*' character after it. Easy enough.
* And for a bare drive name like D:, we just append two characters,
* namely, '\' and '*'. Wow, that was easy too!
*
* Oh well. I can see by the clock that we are out of time now,
* so that's it for this episode of "Fun Facts for Inquiring Minds".
* Bye Kids!
