本文讨论了微软的STL容器类是否线程安全。根据MSDN的回答，STL容器类包括vector、deque、list、queue、stack、priority_queue、valarray、map、hash_map、multimap、hash_multimap、set、hash_set、multiset、hash_multiset、basic_string和bitset。对于单个对象来说，多个线程同时读取是安全的。但如果一个线程正在写入一个对象，那么所有的读写操作都需要进行同步。
STL container classes thread safe(Microsoft C++ implementation)?
Answer from MSDN:
The container classes are vector, deque, list, queue, stack, priority_queue, valarray, map, hash_map, multimap, hash_multimap, set, hash_set, multiset, hash_multiset, basic_string, and bitset.
A single object is thread safe for reading from multiple threads. For example, given an object A, it is safe to read A from thread 1 and from thread 2 simultaneously.
If a single object is being written to by one thread, then all reads and writes to that object on the same or other threads must be protected. For example, given an object A, if thread 1 is writing to A, then thread 2 must be prevented from reading from or writing to A.
It is safe to read and write to one instance of a type even if another thread is reading or writing to a different instance of the same type. For example, given objects A and B of the same type, it is safe if A is being written in thread 1 and B is being read in thread 2.
