title: What are the POSIX cancellation points?
body: <p>What are the POSIX cancellation points? I'm looking for a definitive list of POSIX cancellation points.</p>
  
  <p>I'm asking because I have a book that says <code>accept()</code> and <code>select()</code> are cancellation points, but I've seen sites on the internet claim that they are not.</p>
  
  <p>Also, if Linux cancellation points are different than POSIX cancellation points I want a list of them too.</p>
