Solution 1

See the kill(3)[^] man pages for details of how to kill a process.

I'm sorry but I cannot provide a full tutorial on read pipes between processes, you need to do some reading for yourself. It is also quite difficult to figure out exactly what you are trying to do, beyond killing a process.

Solution 2

You ask for a C solution.

I would solve it in a bash script using kill[^] and mail[^].

For programming in C, use kill[^] and fall back to the mail command line tool to send the notification (via system[^]).

See also wikipedia[^] for an overview on kill and wikipedia[^] on unix mail command line utility.

Tnx Andi!!!in order to kill a process i need to input the process id of the process to be killed.is there a function that gets me yhe process id of another process in which these two processes are not related.

Best regards
Mimi

On the shell, there is ps.
I mean, the process to kill has to be selected somehow. Is it the user who selects from a list (by name?) or is it sufficient to tell the user to run the ps command on the shell and pass over the process id?
