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