CVI Multi-threading

[JoeTestEngineer]

I'm looking at an example "OnePanel" written by NI and can't figure why anyone would want to use "CmtGetThreadLocalVar". I can use a normal locally defined variable in this example and that works fine as it should. Am I missing something? Is there a real application for this "CmtGetThreadLocalVar" routine?

See attached file....

Thanks

Thread Local variables are variables that are globally available, but have local variable value copies. Think of it as a global variable between threads that has a unique local instance. They are uncommonly needed. Usually normal global, local and ThreadSafe variables are all that you need to use. See the document under cvi\bin\MultithreadingOverview.pdf for more information.
