Defect Report UK 023: Correction to Technical Corrigendum 1
An example added by TC1 is wrong.
TC1 added the following example to subclause
#include stdio.h
..... */
int d1, d2, n1, n2, i;
i = sscanf("123", "%d%n%n%d", &d1, &n1, &n2, &d2);

the value 123 is assigned to d1 and the value 3 to n1. Because %n can never get an input failure the value of 3 is also assigned to n2. The value of d2 is not affected. The value 3 is assigned to i.
This should set i to 1, not 3, as %n does not affect the returned assignment count.
Suggested Technical Corrigendum
In the example, change:
The value 3 is assigned to i.
The value 1 is assigned to i.
