Define Documentation

#define IF_DEBUG()

Value:

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

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)

Push a playlist_t onto the device after converting it to a .spl format

Parameters:

device mtp device pointer
pl 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.

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.
