I'm trying to write files containing a UUID to memory cards inside cameras and phones so that I can identify a card that has been seen before when a device is plugged in.

This works:

`#!/usr/bin/python3

#Tag, untag and retag memory cards

import os
import sys
import gphoto2 as gp
from ctypes import *

def main():
cam = gp . Camera ()
cam . init ()
val, tfile = gp . gp_file_open ( "orig.uui" )
p = cam . folder_put_file ( "/store_00010001/DCIM", "elephant.uui",
gp . GP_FILE_TYPE_NORMAL, tfile)
main()

`
It copies a UUID from a text file created by uuidgen to the card in the camera.

However I have completely failed to write a UUID from a Python text string without going via a disk file. I have tried creating a file and using set_data_and_size() but have not found any combination of parameters that will work.

Is there somewhere an example program for set_data_and_size() ?
