title: Where to find eventfd_write documentation?
body: <p>Is there a detailed documentation for eventfd_write?</p>
  
  <p>man eventfd_write brings up the manpage of eventfd.  On that manpage, it mentions eventfd_write() is offered by glibc.</p>
  
  <p>Google only indexed 6 pages of entire gnu's site for eventfd_write.  None of them is related to the documentation.</p>
  
  <p>Any idea where I can find it?</p>
  
  <p>P.S. Another side question (but sort of related): is there a mailing list to ask non-distribution specific questions about glibc? I only see the point of contacts for distribution specific questions.</p>
