184.108.40.206.49 ApiGetNodeId (Opnum 48)
(Protocol Version 3) The ApiGetNodeId method returns the unique ID of the designated node.
The server SHOULD accept an ApiGetNodeId request if the access level associated with the hNode context handle is at least "Read" (section 3.1.4).
error_status_t ApiGetNodeId( [in] HNODE_RPC hNode, [out, string] LPWSTR* pGuid, [out] error_status_t* rpc_status );
pGuid: The address of a pointer that receives a pointer to a Unicode string buffer where the server MUST return the unique ID of the node after successful completion of this method. The server MUST allocate as much memory as is required to return the ID. If the method fails, this parameter MUST be ignored.
rpc_status: A 32-bit integer used to indicate success or failure. The RPC runtime MUST indicate, by writing to this parameter, whether it succeeded in executing this method on the server. The encoding of the value passed in this parameter MUST conform to encoding for comm_status and fault_status, as specified in Appendix E of [C706].
Return Values: The method MUST return the following error codes for the specified conditions.
Return value/code Description
The hNode parameter does not represent a valid HNODE_RPC context handle.
The node represented by the hNode parameter no longer exists in the non-volatile cluster state.
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. The client SHOULD treat errors specified in 220.127.116.11 as recoverable errors and initiate the reconnect procedure as specified in section 18.104.22.168.
