Inside Macintosh: QuickDraw GX Environment and Utilities /: Chapter 6 - Message Manager / Using the Message Manager

Determining the Version of the Message Manager
To determine the current version of the QuickDraw GX Message Manager, you can call the Gestalt function with the gestaltMessageMgrVersion selector 'mess'. The gestaltMessageMgrVersion selector returns a 2-byte value indicating the version of the QuickDraw GX Message Manager that is currently installed. The high-order byte is the major version number and the low-order byte is the minor revision number.
The selector 'mess' is defined in the section "Message Manager Gestalt Selector" beginning on page 6-16.
For more information about the Gestalt function, see the chapter "Gestalt Manager" in Inside Macintosh: Operating System Utilities.
