Thread: zombie to exist after the termination of main program..

Code:

main()
{
pid_t child;
child=fork();

if(child > 0)

{sleep(60);
}

else
{exit(0);
}

}

the above code will create zombie process,which will be adopted by init as soon as parent process will dies.Can any one gimme a code or an alogrithm to keep this zombie proocess alive even after its parent dies...i.e to stop init from adopting it after the termination of main programme
