/*PRQA S 336,602,1302,1307,2017,3122,3132,3200,3209,3335,3408,3602,3625 ++*/

#include <stdio.h>

extern void foo(void)
{
    void *pv;

    scanf("%p",  &pv);                /*              */

    scanf("%lp", &pv);                /* Message 0197 */
    scanf("%hp", &pv);                /* Message 0197 */

}
