title: Good reference for C++ iostreams?
body: <p>I am struggling understanding C++ iostream library -> "What and why only" . I found a library 
  at IBM named "IBM C/C++ Legacy Class Libraries Reference" , which can seen here:</p>

  <a href="http://www.bluefern.canterbury.ac.nz/UCSC%20userdocs/ForUCSCWebsite/C/AIX/legacy.pdf" rel="nofollow">Alternate link</a></p>
  
  <p>i want to ask that , is this good reference for c++98 iostream (it goes with standard?)?
  or any other reference? . 
  i am looking for deep and good tutorial on it, why things happen etc .</p>
  
  <p>I can't buy c++ iostream and locales book ( pocket problem:) ) , so don't tell me to buy it.</p>
