To elaborate more. New process image will not have the existing threads and
user defined data declared in current process will be wiped out. Parent can
do is to wait for the child status by calling wait().
for example
main()
{
pid = fork();
if (child) {
exec("ls"); /// here 'ls' will replace the child process
no matter how many threads it has
}
else // parent
wait for child
}
