my 1st linux driver

[jah]

thanks for reading my post.
need some linux hints... need to be able to make the user land apps aware, after a ioctl(), of LARGE buffers created in a kernel driver. dont want to move buffer content only translate pointer values if possible.

i have especially looked at: get_user()
also: copy_from_user(), strncpy_from_user()
and these attempt to work with value not the pointer(s).

thanks.
