# Cogl experimental API

## About the experimental API

Cogl has some experimental API developers are welcomed to play with. The main drawback when using those is that there is no API stability guarantee, functions flagged as experimental could be changed or removed in future versions of the library. To use this experimental API you will need to define `COGL_ENABLE_EXPERIMENTAL_API` before including `<clutter/clutter.h>` or `<cogl/cogl.h>`.
