Description

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 signalled. The default value of errorp is t .
