Sorry Walter and Magnus. I didnt expose my quest properly. The input of
function is a variable with the value of the oid "netdotmediaipadress" and
the size of this value. This function make two things: save the input value
in a string in the standard ip adress format. And print the input value at
the same format. The print is ok, then my problem is save the value in a
formatted string. Thanks
