#include stdio.h
#include stdlib.h
#include sys/types.h
#include sys/stat.h
#include unistd.h
#include fcntl.h

Sorry the first file's name should be gpio.cpp.
The code I have posted is based on the code at the following link:

I have attached my files(gpio.cpp and gpio.h) and hope it could help you.

Pad control registers can only be changed in kernel space. You could write a
kernel driver or do it the right way and use device tree.
See

If you don't want to use it directly, you can use the generated files as an
example.
