Returns a binary value from the cluster database.
Syntax
DWORD ResUtilGetBinaryValue(
[in] HKEY hkeyClusterKey,
[in] LPCWSTR pszValueName,
[out, optional] LPBYTE *ppbOutValue,
[out] LPDWORD pcbOutValueSize
);
Parameters
[in] hkeyClusterKey
Key in the cluster database that identifies the location of the value to retrieve.
[in] pszValueName
Pointer to a null-terminated Unicode string containing the name of the value to retrieve.
[out, optional] ppbOutValue
Address of the pointer to the retrieved value.
[out] pcbOutValueSize
Pointer to a DWORD in which the size in bytes of the buffer pointed to by ppbOutValue is returned.
Return value
If the operations succeeds, the function returns ERROR_SUCCESS.
If the operation fails, the function returns a system error code. The following is a possible error code.
| Return code | Description |
|---|---|
|
There was an error allocating memory for the value. |
Remarks
The ResUtilGetBinaryValue utility function takes care of allocating the necessary memory for the value and then calls the Cluster API function ClusterRegQueryValue. When you are finished with the allocated memory, you must call the function LocalFree to release it.
