開放時間

跨平台多執行緒設計！ OpenTime for C++，超好用的Time！

OpenLinyou專案設計了一個跨平台的伺服器框架。在 VS 或 XCode 中編寫程式碼，無需任何變更即可在 Linux 上運行，甚至可以在 Android 和 iOS 上運行。 OpenLinyou：https://github.com/openlinyou

跨平台支援

Linux和Android使用epoll，iOS和Mac使用kqueue，其他系統（Windows）使用select，因此io數量不能超過64。

編譯執行

請安裝cmake工具。使用cmake，您可以建立VS或XCode專案並在VS或XCode上編譯和運行它。原始碼：https://github.com/openlinyou/opentime

 # Clone the project
git clone https://github.com/openlinyou/opentime
cd ./opentime
# Create a build project directory
mkdir build
cd build
cmake ..
# If it's win32, opentime.sln will appear in this directory. Click it to start VS for coding and debugging.
make
./test
