C API Reference#
This section documents the Gurobi C interface. This manual begins with a quick overview of the functions in the interface, and continues with detailed descriptions of all of the available interface routines.
If you are new to the Gurobi Optimizer, we suggest that you start with the Getting Started Knowledge Base article for general information. This also includes Tutorials for the different Gurobi APIs. Additionally, our Example Tour provides concrete examples of how to use the routines described here. We will point to sections or examples of this tour whenever it fits in this overview.
