If i create a child process and want to know how much output it has produced
(total of all files written inc. stderr,stdin) after it has exited (via call
from parent), what if any is the best way to achieve it?
is there a system call to help me here - i've had a look at ioctl() but it
doesnt seem provide the info i need - please correct me if i am wrong.
many thanks in advance.
