title: How to fopen() on the iPhone?
body: <p>The iPhone SDK docs claim fopen() is a supported method of file access but I am unable to get it to return a FILE handle.  I am accessing a directory which is included in my project.  I have tried fopen "filename","dir/filename","./filename","./dir/filename","/dir/filename" all returning with a null pointer.  Some people report using it with no issue so I am sure it is something simple!</p>
