title: How to get the current playback position with libspotify?
body: <p>I have been writing Spotify support for a project using libspotify, and when I wanted to implement seeking, I noticed that there is apparently no function to get the current playback position. In other words, a counterpart to sp_session_player_seek(), which returns the current offset.</p>
  
  <p>What some people seem to do is to save the offset used in the last seek() call, and then accumulate the number of frames in a counter in music_delivery. Together with the stored offset, the current position can be calculated that way, yes - but is this really the only way how to do it?</p>
  
  <p>I know that the Spotify Web API has a way to get the current position, so it is strange that libspotify doesn't have one.</p>
