C and C++ examples – PolySync Support Center

PolySync ships with an extensive C and C++ API that you can use to quickly prototype applications. Sometimes it helps to have some examples, so we've included a variety for you to try.

Before you can clone the example application repositories you will need to install git. If you intend to build C++ examples you will also need to install cmake.

$ sudo apt-get install git cmake
$ git clone git@github.com:PolySync/PolySync-CPP-Examples.git      # clones C++ examples
$ git clone git@github.com:PolySync/PolySync-C-Examples.git        # clones C examples
