Default sigint form within a c prog

How do I send the kill signal to a program from within another program?

I understand I can do this

kill (pid, SIGINT);

But how do I get the pid for the program I want to kill from within the program I want to issue the signal from?

Thanks for any information.

The best tutorial is probably the /usr/src/bin/ps source code...

There's also /proc, but that isn't as portable, as not every system always mounts /proc (OK, most don't nowadays.)

Generally speaking, you'll need to hit the kvm_* calls, which are documented in man pages, but reading the ps source is probably the easiest way to figure out what's up and see it in action before diving into the man pages to make sure you get your implementation right.

are the 2 processes related in some way or are you just killing some unrelated process?

maybe checkout the source code for the ptools pgrep or pkill?
