18.104.22.168.120 ApiOpenNetworkEx (Opnum 121)
(Protocol Version 3) The ApiOpenNetworkEx method establishes context on the server about the interaction of a client with the specified cluster network by using the current RPC connection. ApiOpenNetworkEx returns a context handle so that the client can refer to the context that is created in subsequent method calls.
Servers SHOULD<90> support this method.
There are several ways by which the client can determine the name of the cluster network to specify for the lpszNetworkName parameter. A cluster network can have a well-known name if the cluster network was configured as such by using implementation-specific methods between servers. Optionally, a client can use ApiCreateEnum with enumeration type CLUSTER_ENUM_NETWORK, as specified in section 22.214.171.124.8. This method obtains a list of all cluster network names in the cluster state. The client can then examine names or open networks to call additional methods in order to determine which networks to operate on.
The server SHOULD accept an ApiOpenNetworkEx request if its protocol server state is read-only and MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.
HNETWORK_RPC ApiOpenNetworkEx( [in, string] LPCWSTR lpszNetworkName, [in] DWORD dwDesiredAccess, [out] DWORD* lpdwGrantedAccess, [out] error_status_t* Status, [out] error_status_t* rpc_status );
lpszNetworkName: A null-terminated Unicode string that contains the name of the cluster network for which to establish context on the server.
dwDesiredAccess: The value for this parameter is the same as specified for dwDesiredAccess in ApiOpenClusterEx.
lpdwGrantedAccess: The value for this parameter is the same as specified for lpdwGrantedAccess in ApiOpenClusterEx.
Status: Indicates the status of this operation. The server MUST set Status to the following error codes for the specified conditions.
dwDesiredAccess indicates a level of access exceeding what the client is entitled to (section 3.1.4).
dwDesiredAccess is invalid, as specified earlier in this section.
The server does not support this method.
A cluster network that matches the name lpszNetworkName was not found in the cluster configuration.
For any other condition, the server MUST set Status to a value that is not one of the values listed in the preceding table. The client MUST treat all values that are not listed in the preceding table the same, except as specified in section 126.96.36.199.
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].
