Are there any plans to support handling of exceptions thrown during joinable thread execution? I recall Usenet discussions with proposals varying from Futures to throwable join(): try { thread.join(); } catch (std::runtime_error& e) { ... } Any ideas?
Doesn't this require a certain amount of compiler support?
Yes.
Why? Corba throws user exceptions across remote procedure calls without changes to the c++ compiler (of course there is an IDL compiler). Also, Rogue Wave has a portable library that does this for threading. In both cases the exception object is serialized across the thread/process boundary and then rethrown within the correct context. You can see more on this at http://www.roguewave.com/support/docs/sourcepro/threadsug/9-4.html
IIRC, some compilers don't support throwing exceptions across thread boundaries...
Right. This can't be done portably.
I assume you mean without library support and correctly written user code that uses the library? Jeff
