23 * @brief (Cross-process, MCer/MCed) Access to SMX structures
25 * We copy some C data structure from the MCed process in the MCer process.
26 * This is implemented by:
28 * - `model_checker->process.smx_process_infos`
29 * (copy of `simix_global->process_list`);
31 * - `model_checker->process.smx_old_process_infos`
32 * (copy of `simix_global->process_to_destroy`);
34 * - `model_checker->hostnames`.
36 * The process lists are currently refreshed each time MCed code is executed.
37 * We don't try to give a persistent MCer address for a given MCed process.
38 * For this reason, a MCer simgrid::mc::Process* is currently not reusable after
44 /** Get the issuer of a simcall (`req->issuer`)
46 * In split-process mode, it does the black magic necessary to get an address
47 * of a (shallow) copy of the data structure the issuer SIMIX process in the local
50 * @param process the MCed process
51 * @param req the simcall (copied in the local process)
