title: What is a blob?
body: <p>I came across a few articles referring to a C++ blob. What this is?</p>
  
  <p>I have seen some code that uses it like this:</p>
  
  <pre><code>char blob[100];
  
  element = lst-&gt;putBlob(blob, strlen(blob));
  </code></pre>
  
  <p>The code is not really important here, I just want to know what a "blob" is.</p>
