Getting the System Version

The following example uses the Version API Helper functions to determine the version of the current operating system, if it is a Server or Client release, and then displays this information to the console. If compatibility mode is in effect, the example displays the operating system selected for application compatibility.

Relying on version information is not the best way to test for a feature. Instead, refer to the documentation for the feature of interest. For more information on common techniques for feature detection, see Operating System Version.
