tty driver

Hi,

I need to implement poll function in my Linux tty driver,
to support poll/select functions in user space.

I have no idea, how to use poll() function in my tty driver, since tty_operations does not support poll function, like file_operations.

Have you any idea, how can I provide in my tty driver supporting poll/select in user level application?

Thank you

In tty we can also implement those functionalities without ioctl.
Pls refer "device control without ioctl" in O'reilly ldd book.
This is avialable online for free.
