Is there any way to accomplish all this in C/C++? First I tried to use popen to open a pipe to the process, but then I can't kill it since it doesn't return the pid. The only thing I can do is to close the output stream by using pclose, but it waits for the process to finish so it's of no use. One possible way to do it is to use popen to get access to the output stream and then use system commands to find out its pid, but there got to be a better way, doesn't it?

The better way is to use platform-specific functions to control processes. However, they are OT here. Ask in a newsgroup for your platform/OS.
