[![MIT licensed](https://img.shields.io/badge/license-MIT-blue.svg)](https://github.com/mutouyun/cpp-ipc/blob/master/LICENSE) [![Build Status](https://travis-ci.org/mutouyun/cpp-ipc.svg?branch=master)](https://travis-ci.org/mutouyun/cpp-ipc)
 
A high-performance inter-process communication using shared memory on Linux/Windows.  
使用共享内存的跨平台（Linux/Windows，x86/x64/ARM）高性能IPC通讯库。
 
 * 需要支持C++17的编译器（msvc-2017/gcc-7/clang-4）
 * 除STL外，无其他依赖
 * 无锁（lock-free）或轻量级shared-spin-lock（`ipc::channel::connect`/`disconnect`）
 * 底层数据结构为循环数组（circular array）
 * `ipc::route`支持单生产多消费，`ipc::channel`支持多生产多消费
