The URL of the file, device, or named socket to access.

Discussion
The file pointer is set to the beginning of the file. You cannot write data to the returned file handle object. Use the readDataToEndOfFile() or readData(ofLength:) methods to read data from it.
When using this method to create a file handle object, the file handle owns its associated file descriptor and is responsible for closing it.
