erts_printf("\n" "BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded\n" " (v)ersion (k)ill (D)b-tables (d)istribution\n"); 但是实际上可以有更多功能 看代码: while (1) { if ((i = sys_get_key(0)) <= 0) erl_exit(0, ""); switch (i) { case 'q': case 'a': case '*': /* * The asterisk is an read error on windows, * where sys_get_key isn't that great in console mode. * The usual reason for a read error is Ctrl-C. Treat this as * 'a' to avoid infinite loop. */ erl_exit(0, ""); case 'A': /* Halt generating crash dump */ erl_exit(1, "Crash dump requested by user"); case 'c': return; case 'p': process_info(ERTS_PRINT_STDOUT, NULL); return; case 'm': return; case 'o': port_info(ERTS_PRINT_STDOUT, NULL); return; case 'i': info(ERTS_PRINT_STDOUT, NULL); return; case 'l': loaded(ERTS_PRINT_STDOUT, NULL); return; case 'v': erts_printf("Erlang (%s) emulator version " ERLANG_VERSION "\n", EMULATOR); erts_printf("Compiled on " ERLANG_COMPILE_DATE "\n"); return; case 'd': distribution_info(ERTS_PRINT_STDOUT, NULL); return; case 'D': db_info(ERTS_PRINT_STDOUT, NULL, 1); return; case 'k': process_killer(); return; #ifdef OPPROF case 'X': dump_frequencies(); return; case 'x': { int i; for (i = 0; i <= HIGHEST_OP; i++) { if (opc[i].name != NULL) { erts_printf("%-16s %8d\n", opc[i].name, opc[i].count); } } } return; case 'z': { int i; for (i = 0; i <= HIGHEST_OP; i++) opc[i].count = 0; } return; #endif #ifdef DEBUG case 't': p_slpq(); return; case 'b': bin_check(); return; case 'C': abort(); #endif case '\n': continue; default: erts_printf("Eh?\n\n"); } } 好多调试用的功能 希望对大家有用。 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
