Okay, I will try to answer some of these... to the best of my knowledge:

1. `man getppid` getppid() -- returns the parent's PID
2. `man 2 sigaction` This one is pretty detailed, read through the whole man page so you know what is going on.
3. `man 2 pipe` Yep there is a funtion to do that. Otherwise you can do it manually by setting the ouput of the parent as the input of the child -- not sure how well this works. All file handlers are inheritied.
4. Question number 4 is best answered by `man 3 exec` but for the most part:
execv("command","arg1","agr2" ... ).

If you haven't noticed the man pages are very useful if you know what to look for. try `man -k keyword` and you will probably get the right answer. To verify mine that is what I did using only words found in your questions just to see if they would turn up the right answers -- they did.

Also, you might want to move questions like this to the programming forum where they belong. These aren't really newbie type problems. Just for the future.
