retrieving metadata information from an iPod

Hi all,

There are two ways of getting metadata from an iPod...

The one is to use the mme_explore_info_get() function with a previous call of mme_explore_position_set() with needed 
metadata_types set as flags.

The other way is to refer to the nowplaying table of the qdb.

What is the better way to get metadata-information from an iPod?

RE: retrieving metadata information from an iPod

May depend on what info you are looking for:
  -- querying the nowplaying table (after you received
MME_EVENT_NOWPLAYING_METADATA and not after EVENT_TRACKCHANGE) will give
you info about the track that is being played back at the moment
  -- mme_explore_info_get() + mme_metadata_extract_string() will be
useful for browsing the device or getting metadata (titles) of tracks in
the nowplaying list
     You may want to take a look at the source of the mmexplore command
line utility if have not seen yet: QNX641/target/qnx6/examples/mmexplore
