The way shown here uses a simple function-based approach. Function pointers are among the most powerful tools in C, but are a bit of a pain during the initial stages of learning. This article demonstrates the basics of function pointers, and how to use them to implement function callbacks in C.C++ takes a slightly different route for callbacks, which is … C++ addons | node. Attention geek! Another easy way to do that is to just set y as a global variable and make the callback function change its value whenever it is called. In the function PrintCameraOrientation note how we convert an array to a vector and get a comma-separated list. The mechanism for expressing this interest is to register a callback function with a special module supplied by VMD.
