c - I get the error message:Expression: (L “String is not null terminated” & & 0) -


when run program，i error message.i don't konw how correct it.may help?

char dir[1024]="c:\\users\\username\desktop\\new folder\\pauli\\t3"; void check_dir(char *dir) { int i; = 0; while (dir[i] != '\0') {     if (dir[i] == '/')         dir[i] = '\\';     i++; } strcat_s(dir, sizeof(dir),"\\"); }

sizeof(dir) doesn't expect here. dir char * inside function, gives size of pointer (*). option pass size of array check_dir() function, too:

void check_dir(char *dir, size_t bufsize) {     [...]     strcat_s(dir, bufsize, "\\"); }

(*) in scope dir declared char dir[1024], sizeof(dir) will give expected result.

edit: on side note, check_dir() misnomer here, doesn't check tries normalize string windows path backslashes. call e.g. win32_normalize_path() or that. called check_<foo>() should return (e.g. int) containing result of check.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
