How does the vim “write with sudo” trick work?

This situation always happen: I try to vi a configuration file but I forget to add sudo before it, and when I try to save it, vi prompt me that this file is read only.

How can I change to super-user privilege without get out of vi and re-edit that file?

cmap w!! %!sudo tee > /dev/null %

Add the line in ~ /. Vimrc and do: w!! to keep with sudo

Usually I save it in temp with :w /tmp/foo.txt and then sudo cp.
