c++ - Acess boost ptree across multiple threads -

I would like to create a system that loads options in ptree from an XML-file and fills this ptree with multiple Thread sofer, I have a simple class nude, which is accessible for every thread, in which the methods (IDs) and mills () Unfortunately, ptree does not look threadsof, so the program crashes a lot, is there any way to create country threadsof? Or is there a better solution together?

You can use the patron template described structural interactive.

In fact, instead of a plain ptree instead of a guardian will make a parent an opaque structure that holds a mutex with its data. The only way to access the data is through a guardian_lock , which will be < Code> mutex .

  Parents & lt; Ptree & gt; Xml; // thread 1 {guardian_lock & lt; Ptree & gt; (Xml) lock; Lock-> Put ("a", "b"); } // thread 2 {guardian_lock & lt; Ptree & gt; (Xml) lock; Lock-> Put ("c", "d"); }  

As you can only access the internal ptree through the lock, and lock the locked mute, you will never have a running position .
