How to use xgboost.dll library?

Hi! I have to write a program of xgboost in C language. I downloaded the xgboost.dll library as the C API tutorial explains. How do I have to use this library? Do I have to write something like #include “xgboost.dll” in my project? I don’t find any tutorial about it.

This is a nice place to start:

Thank you edgRB for your help, but actually the tutorial you mentioned is the one I used to install the xgboost.dll library but where I did’n find how to use library.
