So, I have this function,

|bit FileIsBusy(char[] fn)
|{
|  File f = new File();
|  try
|  {
|    f.open(fn);
|  }
|  catch (Exception e)
|  {
|    return(true);
|  }
|  f.close();
|  return false;
|}

this work, however, if I change "Exception" for "FileException", it does not work.  if you go to,

http://www.digitalmars.com/d/phobos.html#file

you'll see that it's suppose to be a FileException.  Is this correct?  I don't understand.

thanks,

josé

That link you gave is for std.file - you're using std.stream. std.stream.File throws std.stream.OpenException when it can't open/create a file.

One quick way to figure out what's going on is to do this:

    catch (Object o)
    {
        printf("threw %.*s\n", o.classinfo.name);
    }

FileException is in std.file. The exception thrown by std.stream.File.open is an OpenException, which subclasses StreamFileException (which subclasses StreamException not FileException). I will document the exceptions thrown by the stream classes and send the doc to Walter.

Where can I find the current definition of the FileException class, or whatever it is now?

I tend to use the find in files function in TextPad to scan "dmd\src\phobos\" and all subdirectories for "*.d" containing the text I am after, in this case "FileException", results include:

std\file.d(59): class FileException : Exception

meaning dmd\src\phobos\std\file.d is the file you're after.
