cpp-ipc - C++ IPC Library

MIT licensed Build Status

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）
