Adding Multitasking Capability to Applications Using Multiprocessing Services
|
Multiprocessing Services 2.0 runs on system software Mac OS 8.6 and later. All PowerPC Macintosh computers are supported except for 6100/7100/8100 and 5200/6200 series computers.
Note
Multiprocessing Services 1.0 functions can run on System 7.5.2 and later if the Multiprocessing Services 1.x shared library is available. Pre-2.0 versions of the library were installed as part of system software for Mac OS 8 through Mac OS 8.5 but must be explicitly installed for earlier releases. The 1.x versions of the Multiprocessing Services library can run on all PowerPC Macintosh computers.
Unlike earlier versions of Multiprocessing Services, you can create and execute preemptive tasks with virtual memory turned on.
Note that under Mac OS 8.6, Multiprocessing Services allows your application to create preemptive tasks within your application's process (or execution context). However, the individual applications are still cooperatively scheduled by the Process Manager. In Mac OS X, both applications and tasks created by applications will be preemptively scheduled. Multiprocessing Services is Carbon-compliant, so applications built following the Carbon specification can run transparently on both Mac OS 8 and Mac OS X systems.
