With what functions i can write my program in /etc/init.d with c++ to start every time the computer starts ? (like in windows with RegOpenKey,RegSetValueEx..............) ?

I'm sorry, this is pretty unclear. Linux does not use a registry like windows, typically starting a linux daemon is as easy as making an init script for the actual executable and linking it to the correct runtimes which is a process entirely done outside c++. For example how apache starts in your distribution (cat /etc/init.d/httpd or /etc/init.d/apache2 in all likelihood) you can compare that to sshd or mysql to get an idea of what is required and optional.

If you just want to start something at boot-up, use rc.local. You can compile your program and place the binary in, say, /bin. Then edit /etc/rc.local and add a line like this:

/bin/my_prog &

Remember to put the '&'. Else, your machine may hang while booting.

Hi

Another easy way to run something at reboot is to use cron. Put something like this in your crontab:

@reboot /bin/my_prog
