I'm talking about the case where the developer knows he wants case sensitivity. In that case, you have to know whether or not the file system is case sensitive to know whether or not "file.c" would get opened if the application tried to open "file.C".
What? I thought the use case we were talking about is where you have a filename and you want to make a guess about what kind of data it contains, based on the extension. I don't think I've ever wanted to find out whether a file will get opened if I use the wrong case. I just trust that the filename I'm given is suitable for passing to open(), whatever case it might have. I also can't think why you might be worried about that just for the extension, and not the rest of the pathname. -- Greg
