## 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](https://github.com/microsoft/vcpkg/blob/master/README.md) 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](https://github.com/microsoft/vcpkg/blob/master/README_zh_CN.md)方式安装，如`vcpkg install cpp-ipc`
