Unity supports native plug-ins, which are libraries of unmanaged code written in languages such as C, C++, and Objective-C. Native plug-ins let the managed C# code you write call functions from these libraries, so you can integrate middleware libraries and reuse existing C and C++ code. You can use both precompiled libraries and source code files as native plug-ins.
Unity also provides native APIs that let your plug-ins interact directly with Unity engine systems such as rendering, profiling, and logging, without going through managed code. For more information, refer to Native plug-in APIs. For platform-specific information on native plug-ins, refer to the relevant section under Platform development.
