Hi again!
No you got an error. 0, or FALSE, means "error" which you can read in
the documentation for the function:
http://developer.gimp.org/api/2.0/libgimp/libgimp-gimpdrawable.html#gimp-drawable-set-pixel
There you can also read that the num_channels parameter shall be the
"The number of channels for the pixel.". You try to pass the number of
bits, 24. Even that is wrong since you create the layer with an alpha
channel, so the correct wrong thing to pass would be 32.
