OpenClusterResourceEx function (clusapi.h)
Opens a resource and returns a handle to it.
Syntax
HRESOURCE OpenClusterResourceEx(
[in] HCLUSTER hCluster,
[in, optional] LPCWSTR lpszResourceName,
[in] DWORD dwDesiredAccess,
[out, optional] DWORD *lpdwGrantedAccess
);
Parameters
[in] hCluster
Handle to a cluster.
[in, optional] lpszResourceName
Pointer to a null-terminated Unicode string containing the name of the resource to be opened.
Resource names are not case sensitive. A resource name must be unique within the cluster. The name is set when the resource is created and can be changed using the SetClusterResourceName function.
[in] dwDesiredAccess
The requested access privileges. This may be any combination of GENERIC_READ (0x80000000), GENERIC_ALL (0x10000000), or MAXIMUM_ALLOWED (0x02000000). If this value is zero (0) and undefined error may be returned. Using GENERIC_ALL is the same as calling OpenClusterResource.
[out, optional] lpdwGrantedAccess
Optional parameter that contains the address of a DWORD that will receive the access rights granted. If the DesiredAccess parameter is MAXIMUM_ALLOWED (0x02000000) then the DWORD pointed to by this parameter will contain the maximum privileges granted to this user.
Return value
If the operation was successful, OpenClusterResourceEx returns a handle to the opened resource.
| Return code | Description |

The operation was not successful. For more information about the error, call the GetLastError function. If the target server does not support the OpenClusterResourceEx function (for example if the target server is running Windows Server 2008 or earlier) then the GetLastError function will return RPC_S_PROCNUM_OUT_OF_RANGE (1745). |
