title: Logging library for C
body: <p>I am looking for a productive and simple logging library for C, which can output the log to a file. Displaying messages in the log I want to make like this: </p>
  
  <pre><code>date-time tag message
  </code></pre>
  
  <p>It would be nice to control the level of detail of messages and control the size of the file.</p>
  
  <p>I found two projects that are suitable for me. It <a href="http://log4c.sourceforge.net/" rel="noreferrer">log4c</a> and <a href="http://code.google.com/p/nglogc/" rel="noreferrer">nglogc</a>.</p>
  
  <p>log4c seemed too big. nglogc quite fit, but also has a redundant functional. maybe you tell me more variants?</p>
