CLUSCTL_RESOURCE_STORAGE_GET_DIRTY control code
Retrieves a list of dirty volumes on the disk resource. 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_DIRTY,
NULL, // lpInBuffer - Not used
0, // nInBufferSize - not used
lpOutBuffer, // output buffer: array of dirty volume numbers
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 [out]
-
Pointer to an output buffer to receive the array of DWORD values containing the volume numbers of the dirty volumes on this disk resource.
-
cbOutBufferSize [in]
-
The allocated size (in bytes) of the output buffer.
-
lpBytesReturned [out]
-
Returns the actual size (in bytes) of the data resulting from the operation.
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.
