Mixed Mode Manager Routines

This section describes the routines provided by the Mixed Mode Manager. You can use these routines to

• create and dispose of routine descriptors
• execute routines described by routine descriptors

In general, you need to call these routines only from PowerPC code. To maintain a single source code base for your software, however, you can call Mixed Mode Manager routines from 680x0 code, as long as you set the USESROUTINEDESCRIPTORS compiler flag to false (its default setting). To compile code for the PowerPC environment, you should set the USESROUTINEDESCRIPTORS flag to true.

See "Using the Mixed Mode Manager" beginning on page 2-14 for detailed instructions on using these routines.
