Hi,
I know we can use kill_fasync( ) to send signal the user process that data has arrived and maybe by using like ioctl method the user process can get the event data(buffer).
Question: Is there any way wherein we can send event data(buffer) back to the user process. kill_fasync( ) takes three parameters async_queue, SIGIO, band. What I am looking is not only that the driver to signal the user process that data has arrived, but also can send the data back. -or- kill_fasync is used only to notify the user process.
Thanks for your help in advance.
With regards, Anil
