File access outside sandbox?

My application needs to access files that the user has permissions to read. It also needs to write files to directories that the user has permission to write to. Code is C++ and files are accessed w/ fopen. Building with XCode the application seems to be restricted to the /Users/name/Library/Containers/AppName/Data directory. How do I remove this restriction? (Both during develpment and deployment)
