a thread safe stack?

[Gernot Frisch]

Hi,
I need a stack I can access from many threads simultanously. How do I
archive it? (No STL, please - real code)

--
-Gernot
int main(int argc, char** argv) {printf
("%silto%c%cf%cgl%ssic%ccom%c", "ma", 58, 'g', 64, "ba", 46, 10);}

I haven't tried it out, but there is a nonblocking stack in
http://www.musicdsp.org/files/ATOMIC.H .

What, STL is fake code?

Anyway, you are in the wrong newsgroup -- there isn't a way to do this w/
standard C++ language constructs in a platform independent way. You need to
take this question to a forum that discusses your OS and/or framework library.

Your question is off-topic here. Try either
comp.for.men.c++.no_fucking_stl - or - comp.programming.threads.

Sorry. I can't use STL in this project. I love STL for other projects.
If I set a "locked" bit on the buffer, that would be enough, no?

Contrary to popular belief, it is possible in standard C++ to guarantee
mutal exclusion (such as Dekker's algorithm). Though, such methods are
never very efficient, and as such its best to use OS-specific calls.

Note: *everyone* asks this when starting out. No, just setting a
busy/in-use flag will not guarantee serialize access to the stack!

The ACE framework (http://www.cs.wustl.edu/~schmidt/ACE.html) contains non
STL containers as well as MT support

What people are trying to tell you is that C++ does not have a
"locked" bit. The language has no support for multitasking at all.
All such code relies on platform-specific extensions supplied by the
operating system, and can differ with different operating systems and
compilers/libraries.

So it's off-topic here and needs to be asked in either a group that
specifically supports threads, such as comp.programming.threads as
suggested, or a group for your particular compiler/OS combination such
as or one of Microsoft's
support groups in the family.

It is not a C++ language question.
