CLUSCTL_NODE_BLOCK_GEM_SEND_RECV control code
TBD. Applications use this control code as a ClusterNodeControl parameter.
ClusterNodeControl(
hNode, // node handle
hHostNode, // optional host node
CLUSCTL_NODE_BLOCK_GEM_SEND_RECV, // this control code
lpInBuffer, // input buffer
nInBufferSize, // input buffer size
lpOutBuffer, // output buffer: string
cbOutBufferSize, // allocated buffer size (bytes)
lpcbBytesReturned ); // resulting data size (bytes)
Parameters
The following control code function parameter is specific to this control code. For complete parameter descriptions, see ClusterNodeControl.
-
lpOutBuffer
-
A pointer to an output buffer that receives the data for the operation, or NULL.
Return value
ClusterNodeControl returns one of the following values.
-
ERROR_SUCCESS
-
0
The operation completed successfully. The lpcbBytesReturned parameter points to the actual size of the returned data.
-
ERROR_MORE_DATA
-
234 (0xEA)
More data is available. The output buffer pointed to by lpOutBuffer was not large enough to hold the data resulting from the operation. The lpcbBytesReturned parameter points to the size required for the output buffer.
-
If any other value is returned, then the operation failed. The value of lpcbBytesReturned is unreliable.
