title: Python and C++ sharing the same memory resources
body: <p>Let's say we are using <strong>Python</strong> and calling some <strong>DLL</strong> libraries written in <strong>C++</strong>. We open a very large dataset in Python and then we would like to call a library written in C++ and add an array with that opened data as a parameter. Library would do something with that array and then return it back to Python code.</p>
  
  <p>So the question is: Is it possible to use the same location of a memory?
   Because in that case we do not need to copy a huge amount of data two times.</p>
