Shell/commands/scripting/c questions

1. Can anyone explain me what the line
x=signal(SIGINT,nh);
does?


2. How do I write a command to print the longest line in a file?

3. How do I write a command to print the last word of every line of a file using sed?

4. What exactly does this line do?
:%s/^\([0-9]\)\([0-9]\)/\2\1/g^M
Assuming it is run from vi.


Thank you all for your time.
