Everyone's responses have been helpful so far :-) I have another question. I've decided to use the 'copy_from_user' function, but I don't know how I'm supposed to discover the userspace address I need to copy from. The data I want to get into the kernel is in a variable in a userspace function. -Jeremy -- ---------------------------- Jeremy C.
