enum-registry-value subkey index &key root max-name-size max-buffer-size expected-type errorp => name , data-type , data , error-code
A string specifying the name of the key.
An integer.
A keyword or handle.
An integer.
An integer.
A keyword or
t
.
A boolean.
The function
enum-registry-value
allows the values of subkey under the key
root
to be enumerated.
subkey
and
root
are interpreted as described for create-registry-key. The default value of
root
is
:user
.
index specifies which value to return, with 0 being the first item.
max-name-size specifies the maximum length of the returned name. If the name is longer than this, an error is signalled. The default value of max-name-size is 256.
max-buffer-size specifies the maximum length in bytes of the value. The value is longer than this, an error is signalled. The default value of max-buffer-size is 1024.
If the value exists (that is, index is not too large), then the return values are the name, data type and data associated with the value in the registry. The argument expected-type controls how certain data types are converted to Lisp objects as follows:
The default value of
expected-type
is
t
.
If an error occurs and
errorp
is true, then an error is signalled. Otherwise, the return values are
nil
,
nil
,
nil
and the Windows
error-code
. The default value of
errorp
is t.
