#define IF_DEBUG (  ) 

Value:

if(DEBUG_ENABLED) {\
                     printf("%s:%u:%s(): ", __FILE__, __LINE__, __func__); \
                   } \

Function Documentation

int is_spl_playlist ( PTPObjectInfo *  oi  ) 

Decides if the indicated object index is an .spl playlist.

Parameters:
oi object we are deciding on
Returns:
1 if this is a Samsung .spl object, 0 otherwise

Referenced by LIBMTP_Get_Playlist(), and LIBMTP_Get_Playlist_List().

int playlist_t_to_spl ( LIBMTP_mtpdevice_t device,
LIBMTP_playlist_t *const   pl 
)

void spl_to_playlist_t ( LIBMTP_mtpdevice_t device,
PTPObjectInfo *  oi,
const uint32_t  id,
LIBMTP_playlist_t *const   pl 
)

Take an object ID, a .spl playlist on the MTP device, and convert it to a playlist_t object.

Parameters:
device mtp device pointer
oi object we are reading
id .spl playlist id on MTP device
pl the LIBMTP_playlist_t pointer to be filled with info from id

int update_spl_playlist ( LIBMTP_mtpdevice_t device,
LIBMTP_playlist_t *const   new 
)

Update a playlist on the device. If only the playlist's name is being changed the pl->playlist_id will likely remain the same. An updated track list will result in the old playlist being replaced (ie: new playlist_id). NOTE: Other playlist metadata aside from playlist name and tracks are ignored.

Parameters:
device mtp device pointer
new the LIBMTP_playlist_t to convert (pl->playlist_id will be updated with the newly created object's id)
Returns:
0 on success, any other value means failure.
