Jump to a position in the playlist.

int mmplaylist_current_pos_set( mmplaylist_t *pl, int new_pos, mmplaylist_seek_offset_t whence )
Jump to a position in the playlist. The new position is specified as the index of the entry that you're seeking to. This operation can be very expensive, so the application may first check the value of the seek_fast field in the mmplaylist_props_t structure to determine whether this operation can be completed quickly or not.
