ClusterRegOpenKey function (clusapi.h)

  • Article

Opens an existing cluster database key.

Syntax

LONG ClusterRegOpenKey(
  [in]  HKEY    hKey,
  [in]  LPCWSTR lpszSubKey,
  [in]  REGSAM  samDesired,
  [out] PHKEY   phkResult
);

Parameters

[in] hKey

Handle to a currently open key. This parameter cannot be NULL.

[in] lpszSubKey

Pointer to a null-terminated Unicode string specifying the name of the subkey to be created or opened. The lpszSubKey parameter must point to a subkey that:

  • Is a child key of the key identified by hKey.
  • Must not begin with the backslash character ( \ ).
  • Must not be NULL.
The lpszSubKey parameter can point to an empty string, causing ClusterRegCreateKey to return a handle to the database key represented by hKey.

[in] samDesired

Access mask that specifies the security access needed for the new key.

[out] phkResult

Pointer to a handle to the opened or created key.

Return value

If the operation succeeds, the function returns ERROR_SUCCESS.

If the operation fails, the function returns a system error code.

Remarks

Callers should call ClusterRegCloseKey to close the key handle opened by ClusterRegOpenKey when they are done with it.
