$Revision: 5.0.2.4 $
Package: SYSTEM
This variable always holds the stack-group that is currently executing. It is nil before the first mp:stack-group-resume is done. This variable should be treated as read only.
USE OF THIS VARIABLE IS DEPRECATED.
Allegro CL has two models of multiprocessing, the :os-threads model and the non :os-threads model, so named because :os-threads is on the *features* list of versions that use it. This variable is used only by the non :os-threads model. The symbol naming this variable does not exist in versions using the :os-threads model. Conditionalize uses of this symbol in code that might be ported between verrsions with #-os-threads.
Note that in the future, all versions of Allegro CL may use the :os-threads model and code using this variable will not work.
See multiprocessing.htm for general information on multiprocessing in Allegro CL.
The general documentation description is in introduction.htm. The index in index.htm.
