title: Using Vim to find definition when navigation around /usr/include/files
body: <p>I found it was casual to navigate between header files when you want do something under linux. And when I want find a definition of something, for example, <code>struct sockaddr_storage</code>. What I am doing right now is <code>:!find /usr/include/ -type f | xargs grep " struct sockaddr "</code>. It's powerful, but unconvincing for me. </p>
  
  <p>Does there exist an easier way to navigate around .h files like other IDEs, e.g.,VStudio, offer? ( almost C/CPP user am I ) ctags and cscope or tagbar are for project use, can they benefit me in this situation?</p>
