is it possible to keep a copy of the *env in module ?

No. emacs_env, emacs_runtime, and emacs_value objects are only valid within the dynamic extent of the function they are created/passed in. You can't keep them around. The only exception are global references, created by make_global_ref.

instead of copy the pointer, I copy the struct content:

emacs_env genvo;

emacs_env *genv = &genvo;

int

emacs_module_init(struct emacs_runtime *ert)

{

  emacs_env *env = ert->get_environment(ert);

  genvo = *env;

...

}

it is working.
