Hi there,

I wonder if the C++ Standard Template Library (STL) is multi-thread
safe? Does anybody have experience with STL in a multi-threaded
environment?

Thanks
  Thomas

Hmm...that's a bit like asking whether "cars are fast".  Some are, some 
aren't, and of course "fast" is a bit subjective.

Likewise with STL: the classes are defined in such as way that it should be 
fairly easy to make them reentrant, and they don't require the use of a lot of 
global data that would have to be made thread-local.

However, that doesn't imply that every implementation of STL will be safe for 
multithreaded use.  The standard says nothing about threads, so it says 
equally little about the classes being safe for use with threads.
    Later,
    Jerry.
