if(!(pid=fork())){
......
printk("in child process");
......
}else{
.....
printk("in father process");
.....
}
this is a classical example, when the fork() system call runs, it will
build a new process and active it . while the schedule() select the
new process it will run. this is rather normal.
but there is always a confusion in my minds.
because , sys_fork() only copies father process and configure some new
values., and do nothing . so the bridge between the new process and
its following code, printk("in child process"), seems disappear . so I
always believe that the new process should have a pointer which point
the code "printk("in child process");". except this , there are not
any connection between them ?
very confused :(
any help will appreciate !
