Re: [Boost-users] [Boost.thread] Exception handling strategy ?

Exceptions should be caught somewhere.
The software engineer has to make certain of that by adding a try-catch-block on every interface boundary -- such boundaries are usually points where C++ borders on C or the operating system -- e.g. 
        * the main-function, 
        * window message handlers, 
        * thread-functions, 
        * callback handlers provided by certain frameworks 
                e.g. to read from a file descriptor.

I don't think a thread package should provide features for storing exceptions, since this would require a new base class other than std::exception.
You may want to make certain that the exceptions thrown inside a thread function are not simply ignored -- e.g. the string returned from what() can be stored and displayed by the main thread.

Subject: [Boost-users] [Boost.thread] Exception handling strategy ?

Hi there,

is there a recommended strategy for exception (or more generally
error-)handling with Boost.thread ? From what I can see it is not safe to
throw an exception from within a thread, as it is not sure who catches it
(or whether it gets caught at all).

Best, Ruediger
