signal handling in C

I tried to use signal(SIGTERM,&handler()) to handle the Ctrl-C signal, but it didn't work. I also tried it with SIGINT, SIGKILL, SIGSTOP, SIGABRT, etc., but none had worked. what signal is the Ctrl-C?

Ctrl+c sends the SIGINT signal. Try changing the function call to: signal(SIGINT,handler); and remember to place it inside of main()
Hope that helps! ;P

actually I'm doing C coding on Linux :P
the situation is that when I run a background process, the parent doesn't wait() for the child, but the child might still send a SIGCHLD to the parent, in which case the parent needs to handle it. I just want to know if there's a way to find the child's process ID (the source of SIGCHLD) by justing the signal.
