3.1.4.2.80 ApiNodeControl (Opnum 79)

(Protocol Version 3) The ApiNodeControl method instructs the server to initiate, on the specified node, an operation that is defined by the specified control code. The operation is executed on the node where the specified node context handle was obtained.

The server requires that the access level associated with the hNode context handle is "All" (section 3.1.4), if and only if the bitwise AND of dwControlCode and 0x00400000 is not equal to zero.

hNode: An HNODE_RPC context handle that is obtained in a previous ApiOpenNode or ApiOpenNodeEx method call.

lpInBuffer: The input data for the operation that is specified by dwControlCode. See the following sections for the data structures that are required for each dwControlCode.

nInBufferSize: The size, in bytes, of the buffer that is specified by lpInBuffer.

lpOutBuffer: The output data for the operation that is specified by dwControlCode. The output buffer MUST be allocated and provided by the client.

nOutBufferSize: The available size of the buffer that is specified by lpOutBuffer, as allocated by the client.

lpBytesReturned: On successful completion of the method, the server MUST set lpBytesReturned to the number of bytes that are written to the lpOutBuffer buffer.

lpcbRequired: If nOutBufferSize indicates that the buffer that is specified by lpOutBuffer is too small for the output data, the server MUST return 0x000000EA (ERROR_MORE_DATA) and set lpcbRequired to the number of bytes that are required for the output buffer. If the method completes successfully and lpBytesReturned is 0x00000000 then the server MUST set lpcbRequired to 0x00000000. In any other condition the client MUST ignore lpcbRequired after this method completes.

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
0x00000000 ERROR_SUCCESS	Success.
0x00000001 ERROR_INVALID_FUNCTION	The node that is designated by hNode does not support the operation that is designated by dwControlCode.
0x0000000D ERROR_INVALID_DATA	The input data was invalid or was incorrectly formatted.
0x00000057 ERROR_INVALID_PARAMETER	The input data was invalid or was incorrectly formatted.
0x000000EA ERROR_MORE_DATA	The nOutBufferSize parameter indicates that the buffer that is pointed to by lpOutBuffer is not large enough to hold the data that resulted from the operation.

For any other condition, this method returns 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 section 3.2.4.6 as recoverable errors and initiate the reconnect procedure as specified in section 3.2.4.6.

Upon receiving this message, the server MUST:

• Determine the number of bytes that are required for lpOutBuffer. If the size indicated by nOutBufferSize is less than the number of bytes that are required for lpOutBuffer, return ERROR_MORE_DATA (0x000000EA), except as specified in the following sub-sections where a different value is returned, and set lpcbRequired to the number of bytes that are required for the output buffer.

• Return either ERROR_INVALID_DATA or ERROR_INVALID_PARAMETER if the input data is invalid or incorrectly formatted. The client MUST treat these two error codes the same.
