| |
Hello,
I'd like to optimize my driver, which receives data through a fifo and gives them to a user space application. In turns this application moves this data into a file.
To avoid several useless copies, I'd like the application to pass to the driver a file descriptor (?) to the driver and then the driver can directly move the received data to that file.
Could anybody give me some example of such scheme ?
Thanks, -- Francis
