[previous] 0196 [next] [U] Unknown length modifier used with 's' conversion specifier, number %s.
Explicitly undefined REFERENCE - ISO:C90-7.9.6.2 Formatted input/output functions

An unknown length modifier is being used in conjunction with a '%s' conversion specifier in a scanf format string.

Length modifiers are used in conjunction with integer and floating conversion specifiers but not with '%s'.

For example: 


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

#include <stdio.h>

extern void foo(void)
{
    char buf[21];

    scanf("%s",  buf);                /*                           */

    scanf("%ls", buf);                /* Message 0196              */
    scanf("%hs", buf);                /* Message 0196              */
}
