title: c++ header file issue
body: <p>I am working on a network sniffer and I need to use the &quot;ws2ipdef.h&quot; header file to parse the information. I am using Codeblocks version 17.12 and I am having the following problem.</p>
  <p>Error: ws2ipdef.h. There is no such file or directory.</p>
  <p>I tried to use #ifndef _READERCOMMUNICATION_H, but it failed. What can I do to fix this problem?</p>
