Hi jonasclown,

For the purpose, you can use wait() or waitpid() function.

If you could not get it on then Either try posting with your trial code so that I will be in a better positon to help you or ask me and I will do the same.

After calling fork do something like following in your code for the child

while (getppid()!=1) //One is the pid of init and if the parent dies new ppid = 1
{
    sleep(10);   
}
//do the rest work here
//THis will ensure that the child does not do any work until it is adopted by init
