hkey
must be set as in opcode 3 (Set)
index (numeric)
should be set to 0 for the first subkey, and incremented for each subsequent subkey. There is no particular order to the subkeys, so do not put any special significance on index.
name (string)
will return the value name corresponding to index.
type (numeric)
will return the type of the value (see types under Set).
value (type depends on type)
will return the value of the named item. See Read for notes on how to map it to support multiple types.
status (f,6)
0 for success, else error code. Error 259 indicates that there are no more values to enumerate.
