threads - blackboard

This folder contains a simple multi-threading example illustrating how to use the Logtalk built-in predicates threaded_wait/1 and threaded_notify/1 for synchronizing threads using shared resources. The example consists of two persons, a student and a teacher, sharing a blackboard chalk and eraser.

This example should preferably be run from the top-level instead of as a notebook to observe the threads output.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

%versions

Start by loading the example and the required library files:

logtalk_load(blackboard(loader)).

Start the producer and the consumer, each one running in its own thread:

threaded_ignore(student::run(10)), threaded_ignore(teacher::run(4)).
