I've searched some answer ,like this

But my problem is that , I can't modify the code of the caller.

Suppose i have a function process() import from other module, and this function will start three threads, and finally return.I can't modify the codes of process(), so how can i catch exceptions of the three threads? Is there any possibility?

Do you mean catching each thread's exceptions separately? Because if not you can just wrap the call to process() with try – Shay Nehmad Mar 10 '15 at 04:55

Actually, crash the process() itself if any thread fail is also acceptable. but it won't!!!! because even thread fail, process() will still return without any error – demonguy Mar 10 '15 at 04:57
Can't you change process() 's code? – Shay Nehmad Mar 10 '15 at 04:59
@ShayNehmad No, that's the key problem – demonguy Mar 10 '15 at 04:59

So I think that this is unfortunately impossible – Shay Nehmad Mar 10 '15 at 05:00
