CLUSCTL_RESOURCE_STORAGE_GET_SHARED_VOLUME_INFO control code
Retrieves information on the specified shared volume. Applications use this control code as a parameter to the ClusterResourceControl function, and resource DLLs receive the control code as a parameter to the ResourceControl callback function.
ClusterResourceControl( hResource, // resource handle
hHostNode, // optional node handle
CLUSCTL_RESOURCE_STORAGE_GET_SHARED_VOLUME_INFO,
NULL, // input buffer (not used)
0, // input buffer size (not used)
lpOutBuffer, // output buffer: value list
cbOutBufferSize, // output buffer size (bytes)
lpcbBytesReturned ); // resulting data size (bytes)
Parameters
The following control code function parameters are specific to this control code. For complete parameter descriptions, see ClusterResourceControl.
-
lpOutBuffer
-
Pointer to a value list of CLUSPOP_BINARY structures. Each binary structure, in turn, contains a CLUS_CSV_VOLUME_INFO structure describing each cluster shared volume associated with the designated resource.
Return value
ClusterResourceControl returns one of the following values.
-
ERROR_SUCCESS
-
0
The operation was successful. The lpcbBytesReturned parameter points to the actual size of the returned data.
-
ERROR_MORE_DATA
-
234 (0xEA)
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.
-
The operation failed. The value of lpcbBytesReturned is unreliable.
