# cpp-ipc - C++ IPC Library
|
||
|
||
[](https://github.com/mutouyun/cpp-ipc/blob/master/LICENSE) [](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），无动态内存分配
|
||
* `ipc::route`支持单生产者多消费者（1vN)，`ipc::channel`支持多生产者多消费者（NvM）
