Makes application-specific information available to the synchronization observer.

Applies to

C/C++ applications only. Other components, such as UltraLite.NET, do not require a separate parameter to handle user data and so have no User Data parameter.

Syntax

The syntax varies depending on the API you use.

Remarks

When implementing the synchronization observer callback function or event handler, you can make application-specific information available by providing information using the User Data parameter.
