I am doing some research on device driver implementation in
DragonFlyBSD. I am unclear on when to use uiomove and when to use
copy{in,out,str,instr}. I noticed the character device example;
/usr/share/examples/kld/cdev/module/cdev.c uses copy... yet hasn't
been updated to use the new cdevsw interface. I have mostly gotten
the example to work using uiomove but have failed to get the example
working with copy... From uio(9) is would seem is the way to go.Joe
