Hi, one other question:

When opening the source file to be read I have my program currently open 
it in read only mode. However if that file is a directory the program 
does not throw an error and continues as normal. Only if I set the mode 
to read and write will the EISDIR error be thrown. Since opening it for 
writing isn't really necessary, would I lose points if I set the program 
to do that for the sake of catching that error, or should I be 
approaching it from a different angle?
