3.1.4.2.38 ApiCloseKey (Opnum 37)

(Protocol Version 3) In response to an ApiCloseKey request from the client, for a successful operation, the server MUST close the handle to the cluster registry key that is specified by the hKey parameter in the client request.

The server SHOULD accept an ApiCloseKey request if its protocol server state is read-only, and the server MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.

The server SHOULD accept an ApiCloseKey request if the client's access level is at least "Read" (section 3.1.4).

Return Values: The method MUST return the following error codes for the specified conditions.

Return value/code	Description
0x00000000 ERROR_SUCCESS	Success.

For any other condition, this method MUST return a value that is not one of the values listed in the preceding table. The client MUST behave in one consistent, identical manner for all values that are not listed in the preceding table.
