c++ and multithreading

[Le Tubs]

Hi

I'm trying to find out some information about the following classes
being thread safe (atomic), ifstream/ofstream. I have looked on google
but have seemed to have gotten more confused before I started.
Is there a good link or refernces that sort of deal with c++ classes &
miltithreading someone could recommend?

Any tips, links or pointers would be greatly appreciated.

Kindest Regards
David

It depends on what you mean by thread safe. Note that thread safety
does not imply atomicity.

Any tips, links or pointers would be greatly appreciated.

Standard C++ knows nothing of multithreading, and consequently,
standard C++ objects are not innately thread-safe, but you can fairly
easily wrap them with your platform-specific synchronization objects.
See this article for a snazzy technique:

Unless your compiler/library vendor makes some special promise,
they are in no way thread safe.
