Now I know that

       The  functions  snprintf()  and  vsnprintf()  do  not write more than size bytes (including the terminating null byte ('\0')). If the output was truncated due to this limit then the return value is the number of characters (excluding the terminating null byte) which would have been written to the final string if  enough space had been available. Thus, a return value of size or more means that the output was truncated.
