使用boost :: thread将c ++对象从一个线程传递到另一个线程的正确方法是什么？

Question

what is the proper way of passing a C++ object (a map, vector, etc.) from one thread to another? I fear race conditions, stale values, etc. I am using boost threads.

Thanks in advance!

Answer 1

This depends solely of what this object "does". If it's self-contained, ie doesn't hold pointers/references to other objects that may be used in the originating thread - there seems to be no problem. If OTOH it does contain references to some data that still may be in use in the originating thread - its access should be synchronized.

And, of course, passing a complex object by-value should be avoided.
