cpp-ipc (libipc) - C++ IPC Library

A high-performance inter-process communication library using shared memory on Linux/Windows.

• Compilers with C++17 support are recommended (msvc-2017/gcc-7/clang-4)
• No other dependencies except STL.
• Only lock-free or lightweight spin-lock is used.
• Circular array is used as the underline data structure.
• ipc::route supports single read and multiple write. ipc::channel supports multiple read and write. (Note: currently, a channel supports up to 32 receivers, but there is no such a limit for the sender.)
• Broadcasting is used by default, but user can choose any read/ write combinations.
• No long time blind wait. (Semaphore will be used after a certain number of retries.)
• Vcpkg way of installation is supported. E.g. vcpkg install cpp-ipc

使用共享内存的跨平台（Linux/Windows，x86/x64/ARM）高性能IPC通讯库

• 推荐支持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spin-lock
• 底层数据结构为循环数组（circular array）
• ipc::route支持单写多读，ipc::channel支持多写多读【注意：目前同一条通道最多支持32个receiver，sender无限制】
• 默认采用广播模式收发数据，支持用户任意选择读写方案
• 不会长时间忙等（重试一定次数后会使用信号量进行等待），支持超时
• 支持Vcpkg方式安装，如vcpkg install cpp-ipc
