I'm reading C99 and C11 which says:

"If n is zero, nothing is written, and s may  be  a  null  pointer. 
Otherwise,  output  characters  beyond  the n-1st  are discarded rather 
than being written to the array, and a null character is written at the 
end of the characters actually written into the array."

and "Thus,  the  null-terminated  output  has  been
completely written if and only if the returned value is nonnegative and 
less than n."
