title: C Standard Libraries and greenhills compiler
body: <p>I would like to ask two questions.(Microcontroller Project)</p>
  
  <ol>
  <li>What is the difference between Runtime library and standard library (For c language)?</li>
  <li>I would like to write a code for microcontroller that will use standard c library. Previously  I used to work in custom defined library environment. But now I have to integrate Standard C libraries. I am going to use Greenhills compiler. My questioins are:
  Do I have to integrate standard C library or Runtime library? how to get these libraries and integrate into the system?</li>
  </ol>
  
  <p>Thank you</p>
