libmtp - The object management API.
Functions
int LIBMTP_Delete_Object (LIBMTP_mtpdevice_t *, uint32_t)
int LIBMTP_Set_Object_Filename (LIBMTP_mtpdevice_t *, uint32_t, char *)
Detailed DescriptionFunction Documentation
int LIBMTP_Delete_Object (LIBMTP_mtpdevice_t *device, uint32_tobject_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.
