25 * @brief (Cross-process, MCer/MCed) Access to SMX structures
27 * We copy some C data structure from the MCed process in the MCer process.
28 * This is implemented by:
30 * - `model_checker->process.smx_process_infos`
31 * (copy of `simix_global->process_list`);
33 * - `model_checker->process.smx_old_process_infos`
34 * (copy of `simix_global->process_to_destroy`);
36 * - `model_checker->hostnames`.
38 * The process lists are currently refreshed each time MCed code is executed.
39 * We don't try to give a persistent MCer address for a given MCed process.
40 * For this reason, a MCer simgrid::mc::Process* is currently not reusable after
