title: Path to in-memory-file without dumping in tmp
body: <p>Is there a way in python to get the path to the <strong>in-memory file</strong>, so it'll behave as a normal file for methods which needs <strong>file path</strong>?</p>
  
  <p>My objective is to protect the file, so avoiding dumping into /tmp.</p>
  
  <p>Trying to read an encrypted file -> decrypt a file into memory -> use its path for other interfaces. </p>
  
  <p><strong>mmap</strong> does not provide path or filename. </p>
  
  <p>Or any alternative solution for this problem ?</p>
