Your Messg->> First of all what is security domain then?? Your Messg-> I don't know ;-) Can anyone help on this!! Your Messg->Here is a bit more detailed explanation: Your Messg->A task created using clone() is just another thread in Your Messg->the same process, because the parent and child share Your Messg->the execution environment. When creating a new task Your Messg->using clone(), you can specify the signal to be sent Your Messg->to the parent when the child dies. The parent should Your Messg->handle this signal as the death of a thread. Your Messg->But if the child executes another program by calling Your Messg->exec() and then dies, the parent should not be Your Messg->notified with the same signal - the process that is Your Messg->dying is not a thread in the parent any more. Hence Your Messg->the check for exec_id's and falling back to SIGCHLD if Your Messg->they don't match. Thanx a ton ...that was a nice explanation..... Regards Ketan *** "..
