There's no memory shared there.
Now try writing an entire program this way. It's not really possible in traditional languages built around the shared memory concurrency model, sadly.

Exactly my point.
So you're talking about a completely uninteresting and trivial case. Congratulations must be in order.

Quote:Original post by truthsayerThat is exactly my objection to the examples in the articles - they introduce shared memory for no reason, as far as I can tell. Perhaps it's a java thing (as I'm not familiar with all the details of java), but in C++ you could use exactly the same design with exactly the same variables but make it completely thread safe by passing around references to local objects instead of using global ones.
[...]There's no memory shared there.[...]
Doh. Before the thread becomes completely derailed...

Oh man, talk about unfriendliness. SiCrane is one of the more knowledgeable people I know on this forum and I know for a fact that he has no intentions but to help others. Dude, you seriously need to chill out.

Nah, not anymore he doesn't... cus he's banned! Wee!
As far as the object mentor articles go:
Thread safety was not a primary concern when writing them, as threading was not not on the docket as far as concerns go for implementation of the problem they are approaching.
