Creates the specified registry key in an offline registry hive. If the key already exists, the function opens it.
DWORD ORCreateKey( _In_ ORHKEY Handle, _In_ PCWSTR lpSubKey, _In_opt_ PWSTR lpClass, _In_opt_ DWORD dwOptions, _In_opt_ PSECURITY_DESCRIPTOR pSecurityDescriptor, _Out_ PORHKEY phkResult, _Out_opt_ PDWORD pdwDisposition );
A handle to an open registry key in an offline registry hive.
A pointer to a Unicode string that contains the name of a subkey that this function opens or creates. The lpSubKey parameter must specify a subkey of the key identified by the Handle parameter; it can be up to 32 levels deep in the registry tree. For more information about key names, see Structure of the Registry.
This parameter cannot be NULL.
Key names are not case sensitive.
lpClass [in, optional]
The class (object type) of this key. This parameter may be ignored. This parameter can be NULL.
dwOptions [in, optional]
This parameter can be 0 or one of the following values.
The key is a symbolic link. The target path is assigned to the L"SymbolicLinkValue" value of the key. The target path must be an absolute registry path. If this option is set, REG_OPTION_NON_VOLATILE must also be set.
If the lpSubKey parameter specifies an existing key, it must have been created with REG_OPTION_CREATE_LINK.
Registry symbolic links should be used only when absolutely necessary for application compatibility.
The key is not volatile; this is the default. The information is stored in a file and is preserved when the system is restarted. The ORSaveHive function saves keys that are not volatile.
pSecurityDescriptor [in, optional]
A pointer to a SECURITY_DESCRIPTOR structure that contains a security descriptor for the new key. If pSecurityDescriptor is NULL, the key gets a default security descriptor. The ACLs in a default security descriptor for a key are inherited from its direct parent key.
A pointer to a variable that receives a handle to the opened or created key. Use the ORCloseKey function to close the key after you have finished using the handle.
pdwDisposition [out, optional]
A pointer to a variable that receives one of the following disposition values.
The key did not exist and was created.
The key existed and was simply opened without being changed.
If pdwDisposition is NULL, no disposition information is returned.
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value is a nonzero error code defined in Winerror.h. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error.
If the dwOptions parameter is set with REG_OPTION_CREATE_LINK but REG_OPTION_NON_VOLATILE is clear, or if the handle to be returned would be a handle to the root key of the hive, the function returns ERROR_INVALID_PARAMETER.
The key that the ORCreateKey function creates has no values. An application can use the ORSetValue function to set key values.
The ORCreateKey function cannot be used to create the root key in an offline registry hive. Use the ORCreateHive function to create the root key and obtain a handle to the key.
The offline registry does not support saving individual keys. Use the ORSaveHive function to save a key and its subkeys in a hive.
