What is ThreadLib?

From the project documentation:

Thread Library is a free library, for use by Macintosh software developers, that implements cooperative multiple thread execution within a single application. Thread Library...

  • does not require any extensions
  • should work with all Macintosh models (from the Plus on up)
  • works with system 7.x and with system 6.x under Finder or MultiFinder
  • runs in native mode on 680x0 and PowerPC* based Macintoshes
  • compiles into a small library of 3 to 8 kilobytes
  • works with the Symantec, Metrowerks, and MPW compilers

The 680x0 version of Thread Library is 2-3 times faster than Apple's Thread Manager. The PowerPC version of Thread Library is about 2 times faster than Apple's Thread Manager.

Every thread has its own stack, and there are no restrictions on the objects that can be allocated on a thread's stack. All other global application data are shared by threads. Context switches are very efficient since they involve only a few operations to save the current thread's state, followed by a context switch to the new thread, and a few instructions to restore the new thread's state.

The "threadlib1.0.sit_.hqx" archive includes:

  • complete source code in C
  • detailed documentation in Microsoft Word 5.0 format
  • prebuilt libraries for 68K and PowerPC programs, including debug versions of the libraries
  • a new interface that mimics Apple's Thread Manager
  • a simple test application that demonstrates how threads may be used
  • an application that compares the speed of Thread Library with the speed of Apple's Thread Manager
  • Metrowerks CodeWarrior project files
  • AppleScript program for automatic builds

The "threadlib1.0d4.cpt_.hqx" archive is an earlier release, from 1994, included for historical reasons.

Historical Note
Apple Trademark guides specify that MacDNS end-user documentation should include "ThreadLib 1.04 © 1994" notice, suggesting that version of ThreadLib was used in at least one Apple product
