c++ - kill after sleep -


i couldnt make program sleep() after using kill(pid,sigterm) can ?

the code i'm using:

kill(pid_of_process_to_be_killed,sigterm); sleep(5); --> not working sleep(5); --> working

the solution is:

kill(pid_of_process_to_be_killed,sigterm); sleep(sleep(5));

but why first sleep after kill return 0 ?

your sleep() call may terminating due receiving signal. check return value. if it's positive, might want sleep() again on value. http://www.manpagez.com/man/3/sleep/:

if sleep() function returns because requested time has elapsed, value returned zero. if sleep() function returns due delivery of signal, value returned unslept amount (the requested time minus time slept) in seconds
