digitalmars.D.learn - Unable to set static data member of a class (results in default value
- Enjoys Math (18/18) Aug 27 2017 I have:
- Adam D. Ruppe (6/7) Aug 27 2017 That's thread-local. Use shared to make it shared across all
- Jonathan M Davis via Digitalmars-d-learn (9/16) Aug 27 2017 Yeah, so the thread with main in it should have the value set, but for e...
I have: class DataSignal : Thread { public: static int dataReadDelay; void run() { while (true) { Thread.sleep(dur!"msecs"(dataReadDelay)); // Read in the new file data } } } in main I have: DataSignal.dataReadDelay = 8000; // initialize a bunch of signals Then when each thread is running they sleep for 0 seconds, and I can verify that dataReadDelay is staying at 0. I have initialized it no where else. This seems like a major bug.

If you're just looking to set it that one value for all threads and not change it, I'd suggest that you just set it directly and make it immutable - or use enum, so it's a manifest constant. If you want to change it though, you will need to use shared and deal with protecting it appropriately when accessing it. - Jonathan M Davisstatic int dataReadDelay;That's thread-local.
