Hi, I am implementing a poll function for my char device, there is a standard procedure of doing it, 1. poll_wait(give yr wait_queues address here); 2. then see if there is something to be read/write, set a mask and return to user. but here drivers dont seem to add the current process to the waitqueue, before calling poll_wait, so does poll_wait does this for them ? regards Amit -- Kernelnewbies: Help each other learn about the Linux kernel.
