title: CRT AND WIN32 API
body: <p>hI,</p>
  
  <p>I'm wondering under windows where the CRT lib is used. In each dll forming the win32 API? Only by software developped under visual studio ?</p>
  
  <p>In other words, is Windows OS perform malloc, write/read on files and so on, by using other thing than CRT? </p>
  
  <p>THanks</p>
