Stores a value in the registry.

win32

set-registry-value data subkey name &key root expected-type errorp => error-code

`data`⇩	A Lisp object.
`subkey`⇩	A string specifying the name of the key.
`name`⇩	A string specifying the name of the value.
`root`⇩	A keyword or handle.
`expected-type`⇩	A keyword or `t`.
`errorp`⇩	A boolean.

error-code

An integer error code or nil.

The function set-registry-value sets the value associated with name in subkey under the key root.

subkey and root are interpreted as described for create-registry-key. The default value of root is :user.

The stored value is derived from data, converted according to expected-type as follows:

Conversion of Lisp objects to registry values
Lisp data	`expected-type`	Registry type
A string	`:string`	`REG_SZ` exactly as in `data`
Lisp value	`:lisp-object`	`REG_SZ` made with prin1-to-string of `data`
An integer	`:integer`	`REG_DWORD` containing `data`
A foreign pointer	`:binary`	`REG_BINARY` containing bytes of one element at the pointer
An array	`:binary`	`REG_BINARY` containing bytes from the array

The default value of expected-type is t.

If an error occurs and errorp is true then an error is signaled. The default value of errorp is t.
