Can I access a C++11 std::map entry while inserting/erasing from another thread?

Question

Can I access (without locking) an std::map entry while another thread inserts/erases entrys?

example pseudo C++:

typedef struct {
   int value;
   in         


        

Answer 1

As long as the threads are not accessing the same address at the same time there will be no problem.

But for a direct answer to your question, no, it is not thread safe so you can't do it without locking without any errors.
