A variable name.
A string specifying the name of the key.
A keyword or handle.
An integer or keyword.
A boolean.
The macro with-registry-key
evaluates body with the variable handle bound to the registry key handle opened as if by calling
(open-registry-key subkey :root root
:access access
:errorp errorp )
subkey and root are interpreted as described for create-registry-key.
If errorp is nil
and subkey cannot be opened then body is not evaluated.
