George Tcl Bliss Post reply Feb 25 (3 days ago) Multi-threaded programming in Tcl is super simple. But, what happens often is that people get confused and scared away by the language used to explain multi-threaded programming, like using mutexes and condition variables. Let me make it clear -- you do not need to know anything about mutexes or condition variables etc. Those can be used for advanced programming, if you ever need them and once you learned the basics. Otherwise, basics are perfectly fine and enough for everyday use. Example: package require Thread; thread::create { #your code goes here} # anything you want to do, the thread exits/closes once your code completes} or set mythread [thread::create]; # this is a long lived thread, you can keep sending your code there, do [thread::release $mythread] to close/exit it. set output [thread::send $mythread {#your code}] or thread::send -async $mythread {#your code} output; vwait output; Although multi-threaded programming is very simple to start with, you only need it in cases where your application reaches 100% CPU usage or you have some code that could block your application from responding for long periods of time, otherwise you just waste memory and reduce performance by needlessly creating and using threads.
