CLUSCTL_CLOUD_WITNESS_RESOURCE_UPDATE_TOKEN control code
Updates the token used to validate a set of credentials for an Cloud Witness resource. Applications use this control code as a ClusterResourceControl parameter.
ClusterResourceControl(
hResource, // resource handle
hHostNode, // optional node handle
CLUSCTL_CLOUD_WITNESS_RESOURCE_UPDATE_TOKEN, // this control code
lpInBuffer, // input buffer
cbInBufferSize, // input buffer size (bytes)
lpOutBuffer, // output buffer
cbOutBufferSize, // output 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 ClusterResourceControl.
-
lpOutBuffer
-
On a successful return, points to a property list that contains the shared access signature (SAS) of the token.
Return value
ClusterResourceControl 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.
