c++ - Is it possible a kill a command launched using system api in C? If not any alternatives? -


i launching command using system api (i ok using api c/c++). command pass may hang @ times , hence kill after timeout.

using as: 

system("command");

i want use this:

run command using system independent api (i don't want use createprocess since windows only) kill process if not exit after 'x' minutes.

i not know portable way in c nor c++ languages. ask alternatives, know possible in other languages. example in python, possible using subprocess module. 

import subprocess  cmd = subprocess.popen("command", shell = true)

you can test if command has ended with

if cmd.poll() not none:     # cmd has finished

and can kill :

cmd.terminate()

even if prefere use c language, should read documentation subprocess module because explains internally uses createprocess on windows , os.execvp on posix systems start command, , uses terminateprocess on windows , sig_term on posix stop it.
