多线程安全的vector设计---借助thread_local变量 thread_local变量简介 thread_local是C++11之后才引入的关键字。thread_local变量与其所在线程同步创建和销毁,并且只能被创建它的线程所访问,也就是说thread_local变量是线程安全的。每个线程在自身TIB(Thread Information Block)中存
Thread-safety Considerations Reads Are Safe: Multiple threads can read elements from a std::vector simultaneously without any problem. Writes Need Synchronization: If at least one thread modifies a std::vector, and any other thread accesses it simultaneously (even if it’s just reading), you mu...

This is a non-thread-safe, fast, special-purpose resource that gets memory from a preallocated buffer, but doesn’t release it with deallocation. It can only grow. An Example Below you can find a simple example of monotonic_buffer_resource and pmr::vector: #include <iostream> #include <...
No contained elements are accessed: concurrently accessing or modifying them is safe. Exception safety No-throw guarantee: this member function never throws exceptions. Copying any instantiation of the default allocator is also guaranteed to never throw. See also allocator Default allocator (class templa...
No contained elements are accessed by the call, but the iterator returned can be used to access them. Concurrently accessing or modifying different elements is safe. Exception safety No-throw guarantee:this member function never throws exceptions. ...
All control block access is thread-safe, however, manipulating the managed object itself is not thread-safe. void foo(std::shared_ptr<T> t) { // Do something with `t`... } void bar(std::shared_ptr<T> t) { // Do something with `t`... } void baz(std::shared_ptr<T> t) ...
Note: A redisContext is not thread-safe.Sending commandsThere are several ways to issue commands to Redis. The first that will be introduced is redisCommand. This function takes a format similar to printf. In the simplest form, it is used like this:...
