[Freeswitch-users] Server Disconnected when SIGINT occured

[lakshmanan ganapathy]

I taught the signal handler will be inherited by the child process. It also
does like that.
After making a call, If I press ctrl + c, the above program printed
PARENT PID: Signal SIGINT is generated
CHILD PID: Signal SIGINT is generated.

So I think the sigal handlers will be inherited to the child.
Anyway I'll also try registering signal handlers in child also, and then
I'll come back with that result.

Thanks....
