Undo from within plugin

[Tibor Bamhor <tiborb95@xxxxxxxxx>]

Hi,

I want for some reason to implement undo within a plugin (window).

I found this call:

gimp_image_undo(GimpImage *image)

I just do not know what whould be put into brackets. Can you advice?

I have this line in my plugin:

image_ID = param[1].data.d_image (I just copy/pasted it from some plugin template), is this what I am searching for?

Or the undo might be done for the layer only, this might be even better...

Thanks
