GPIO and serial IF programming with C language

[OldRolly]

Hi everybody,
I am just starting with a new RPi2B and would like to ask the community if you can give me some hints for accessing the GPIO pins as well as for the programming of serial interfaces from C programs. Which libraries do I need and how can I include these libraries into the gcc compiler?

Maybe you can give me some examples. I have got experience with C programming, however, I am new with the Raspberry Pi stuff and Raspian.

Thanks a lot for your help.

This will give you bare bones access. You could also look at wiringPi.

This seems to be installed as standard in Jessie. It includes all the basic GPIO functions, serial and much more.
I have not used it in anger, I just checked that the header file and library were there. There must be plenty of people around here with far mor knowledge.
