Cross-platform multi-threaded design! OpenJson is the world's best high-performance C json parser
The OpenLinyou project designs a cross-platform server framework. Write code in VS or XCode and run it on Linux without any changes, even on Android and iOS. OpenLinyou：https://github.com/openlinyou
Linux and Android use epoll, iOS and Mac use kqueue, other systems (Windows) use select, so the number of io cannot exceed 64.
Please install the cmake tool. With cmake you can build a VS or XCode project and compile and run it on VS or XCode. Source code:https://github.com/openlinyou/openjson
# Clone the project
git clone https://github.com/openlinyou/openjson
cd ./openjson
# Create a build project directory
mkdir build
cd build
cmake ..
# If it's win32, openjson.sln will appear in this directory. Click it to start VS for coding and debugging.
