Get tracksession information.
#include <mmplayer/mmplayerclient.h> int mm_player_get_current_trksession_info( mmplayer_hdl_t *hdl, mmp_trksession_info_t **trksession_info )
Get information on the current tracksession. In this release, each player can store only one tracksession at a time, so the last tracksession created is always the "current" tracksession.
The library allocates memory for the structure referenced in trksession_info but it's the caller's responsibility to later deallocate that memory.
