C lang reference

sup /prog/

Im looking for a complete reference of C.

What does /prog/ recommend? It has to be free tough, and prefarably in PDF format.

Sorry. The only official complete reference; the C™®© standard™®©, is $349¹. I suggest using C++ instead, a superset of C² that is legally available for free on the web portal³.
