Is it safe to use STL containers STL for multiple threads if there are no inserts and only .find ()?

Question

In C ++, is it safe to use std :: map or std :: vector at the same time in different threads, if you DO NOT insert, just perform .find () operations on it?

Answer 1

In the current C ++ standard, there is nothing to say on the topic of streaming, and therefore does not solve this problem. However, the documentation for a specific implementation of the C ++ standard library should cover it.

Answer 2

This is a specific implementation and is not guaranteed by the standard.
