how to make gdb stop execution when no current breakpoint is avaiable

Question

for example, my code is :

int main(){
    f();
    g();
    while(1){
        h();
    }
    ..
 }

I set break point on f, g. of course, the program will stop at f()/g(), but when I type "c" and then it will keep running. currently I have to type "CTL+C" to stop it. program also be killed.

is there any other graceful ways to exit from gdb without killing program if the program is running?

thanks

I have to type "CTL+C" to stop it. program also be killed.

type "CTL+C" then gdb will catch SIGINT, then type detach and then "Ctrl-D" or quit . gdb will detach from you process and exit. Your program will go on running and its parent process will become init (PID=1)

Update:

 (gdb) info signals SIGINT Signal Stop Print Pass to program Description SIGINT Yes Yes No Interrupt
