Question

So say we have pseudocode like:

super_local_thread()
{
try{
throw err;
}catch(err)
{
throw err2;
}

and we had launched that thread with boost.
We want to chath its error with another thread. How to do such thing?

Answer 1

C++11 specifies a current_exception function (in the standard, section 18.8 Exception Handling) to allow you to do exactly that.

Here’s an MSDN article on transporting exceptions between threads that makes use of this function.

Since you’re using Boost, here’s the Boost documentation for current_exception and Boost article on transporting exceptions between threads .
