More Effective Use of Shared Memory on Linux

An anonymous reader writes "Making effective use of shared memory in high-level languages such as C++ is not straightforward, but it is possible to overcome the inherent difficulties. This article describes, and includes sample code for, two C++ design patterns that use shared memory on Linux in interesting ways and open the door for more efficient interprocess communication."

Re:C++ has bigger memory issues

In fact, forget it; just use an actual OO language instead.

C++ is an actual Object Oriented language, which is of course half the problem.

If you mean a pure OO language like Java, in which everything is an object except for primitives and it takes ten classes and wrappers just to read a file, well then C++ isn't exactly an Object Oriented language as such. Perhaps you mean Smalltalk or the like.

I tell you what though, C++ is still around after all this time. With all the hype surrounding Java, Perl, C#, Python, etc, etc, etc C++ programmers are still there beavering away with the god awful sytax Stroustrup left them with. Even after all the improvments, all the innovation and all the additional research into computer languages, for a hell of a lot of tasks, there is really no real alternative to C++.

I don't say this as a C++ fanboy, even though I am "somewhat" fond of the language when it is used properly, and not in garbled and unreadable line noise. I say this simply as a statement of fact. There is still no successor to C++.

I don't want garbage collection so much as I want a cleanup and rationalisation of the syntax. GC would be nice, but forcing more readable code would be even better.
