Detailed Description

Function Documentation

   int LIBMTP_Create_New_Album (LIBMTP_mtpdevice_t * device, LIBMTP_album_t *const metadata)
       This routine creates a new album based on the metadata supplied. If the tracks field of
       the metadata contains a track listing, these tracks will be added to the album.

       Parameters:
           device a pointer to the device to create the new album on.
           metadata the metadata for the new album. If the function exits with success, the
           album_id field of this struct will contain the new ID of the album.

           • metadata->parent_id should be set to the parent (e.g. folder) to store this track
             in. Since some devices are a bit picky about where files are placed, a default
             folder will be chosen if libmtp has detected one for the current filetype and this
             parameter is set to 0. If this is 0 and no default folder can be found, the file
             will be stored in the root folder.
           • metadata->storage_id should be set to the desired storage (e.g. memory card or
             whatever your device presents) to store this track in. Setting this to 0 will store
             the track on the primary storage.
       Returns:
           0 on success, any other value means failure.

   void LIBMTP_destroy_album_t (LIBMTP_album_t * album)
       This recursively deletes the memory for an album structure
       Parameters:
           album structure to destroy

   LIBMTP_album_t* LIBMTP_Get_Album (LIBMTP_mtpdevice_t * device, uint32_t const albid)
       This function retrieves an individual album from the device.
       Parameters:
           device a pointer to the device to get the album from.
           albid the unique ID of the album to retrieve.
       Returns:
           a valid album metadata or NULL on failure.

   LIBMTP_album_t* LIBMTP_Get_Album_List (LIBMTP_mtpdevice_t * device)
       This function returns a list of the albums available on the device.
       Parameters:
           device a pointer to the device to get the album listing from.
       Returns:
           an album list on success, else NULL. If there are no albums on the device, NULL will
           be returned as well.

   LIBMTP_album_t* LIBMTP_Get_Album_List_For_Storage (LIBMTP_mtpdevice_t * device, uint32_t const
       storage_id)
       This function returns a list of the albums available on the device. You can filter on the
       storage ID.
       Parameters:
           device a pointer to the device to get the album listing from.
           storage_id ID of device storage (if null, all storages)
       Returns:
           an album list on success, else NULL. If there are no albums on the device, NULL will
           be returned as well.

   LIBMTP_album_t* LIBMTP_new_album_t (void)
       This creates a new album metadata structure and allocates memory for it. Notice that if
       you add strings to this structure they will be freed by the corresponding
       LIBMTP_destroy_album_t operation later, so be careful of using strdup() when assigning
       strings.
       Returns:
           a pointer to the newly allocated metadata structure.

   int LIBMTP_Set_Album_Name (LIBMTP_mtpdevice_t * device, LIBMTP_album_t * album, const char *
       newname)
       This function renames a single album. This simply means that the PTP_OPC_ObjectFileName
       property is updated, if this is supported by the device. The album filename should
       nominally end with an extension like '.alb'.
       NOTE: if you want to change the metadata the device display about a playlist you must not
       use this function, use LIBMTP_Update_Album() instead!
       Parameters:
           device a pointer to the device that contains the file.
           album the album metadata of the album to rename. On success, the name member is
           updated. Be aware, that this name can be different than newname depending of device
           restrictions.
           newname the new name for this object.
       Returns:
           0 on success, any other value means failure.

   int LIBMTP_Update_Album (LIBMTP_mtpdevice_t * device, LIBMTP_album_t const *const metadata)
       This routine updates an album based on the metadata supplied. If the tracks field of the
       metadata contains a track listing, these tracks will be added to the album in place of
       those already present, i.e. the previous track listing will be deleted.
       Parameters:
           device a pointer to the device to create the new album on.
           metadata the metadata for the album to be updated. notice that the field album_id must
           contain the apropriate album ID.
       Returns:
           0 on success, any other value means failure.
