title: Erlang error codes, need more details
body: <p>I am trying to use the file:open(....) function in erlang but it doesn't seem to work. I keep getting an {error, eio} exception. </p>
  
  <p>Ive looked into it in the erlang documentation and all i have found is that it is the posix error for input/output... go figure.</p>
  
  <p>The file name im outputting in is in the formation of "C:/directory/file.txt"
  Im not sure if this has something to do with it.</p>
  
  <p>Is there anyway i can make erlang give me a more specific explanation to what is wrong?</p>
  
  <p>Thanks, 
  Jack</p>
