Did you test this?
According to the sscanf man page:
n Nothing is expected; instead, the number of characters consumed
thus far from the input is stored through the next pointer,
which must be a pointer to int. This is not a conversion,
although it can be suppressed with the * assignment-suppression
character. The C standard says: "Execution of a %n directive
does not increment the assignment count returned at the comple-
tion of execution" but the Corrigendum seems to contradict this.
Probably it is wise not to make any assumptions on the effect of
%n conversions on the return value.
