title: Is any special value "all the file" for CXSourceRange in Clang?
body: <p>I want to tokenize cpp file using clang:</p>
  
  <pre><code>// range = all the file
  CXSourceLocation beginning = clang_getLocationForOffset(TU, file, 0);
  CXSourceLocation end = clang_getLocationForOffset(TU, file, 53); // TODO : set actual file length
  CXSourceRange range = clang_getRange(beginning, end);
  
  clang_tokenize(TU, range, &amp;tokens, &amp;numTokens);
  </code></pre>
  
  <p>The code works and i can see actual tokens.</p>
  
  <p>I need to set CXSourceRange for this. In my case it will be always "all the file" from beginning to the end. Is there any special value meaning "all the file"? Otherwise i have to get file size or hardcode any actual value as in example above.</p>
