How to relaunch process after it terminates in C++

OK, I am trying to relaunch a process after it's name, not pid, terminates. Is this possible? Though I do not see how this would help, I am using g++ 4.3-4.4 on Fedora 10, wandering between my x86 and ppc machines. I just recompile. Thanks, Ben.

How is relaunching different from launching ?

Ug. you know what I mean. I don't know how to trigger this when it detects that a certain process has died. Thanks.

Hi

I don't think adding it to the application will be a good idea. You can set up signal handlers, but there are many things to consider, for example shutting down the computer.

A better solution would be to write a shell script to start/restart the process. If you install mysql server on a Debian/Ubuntu system, the daemon is run by a shell script that checks for crashes among many other things. Take a look at the /usr/bin/mysqld_safe script.
