Function Documentation

int LIBMTP_Delete_Object (LIBMTP_mtpdevice_t * device, uint32_t object_id)

This function deletes a single file, track, playlist, folder or any other object off the MTP device, identified by the object ID.

If you delete a folder, there is no guarantee that the device will really delete all the files that were in that folder, rather it is expected that they will not be deleted, and will turn up in object listings with parent set to a non-existant object ID. The safe way to do this is to recursively delete all files (and folders) contained in the folder, then the folder itself.

Parameters:

device a pointer to the device to delete the object from.
object_id the object to delete.

Returns:

0 on success, any other value means failure.

int LIBMTP_Set_Object_Filename (LIBMTP_mtpdevice_t * device, uint32_t object_id, char * newname)

This function renames a single file, track, playlist, folder or any other object on the MTP device, identified by an object ID. This simply means that the PTP_OPC_ObjectFileName property is updated, if this is supported by the device.

Parameters:

device a pointer to the device that contains the the file, track, foler, playlist or other object to set the filename for.
object_id the ID of the object to rename.
newname the new filename for this object. You MUST assume that this string can be modified by the call to this function, since some devices have restrictions as to which filenames may be used on them.

Returns:

0 on success, any other value means failure.
