[previous] 0469 [next] [C] Bitwise not '~' requires integral operand.
Constraint violations REFERENCE - ISO:C90-6.3.3.3 Unary Arithmetic Operators - Constraints

This is a constraint error

Check the type of the operand. The operand of the '~' operator must be of integral type. For example: 


/*PRQA S 2213,3198,3198,3199,3203,3408,3447,3804,3805,4130 ++ */

struct ST { int x; };

extern struct ST field;
extern int *p;
extern float f;
extern unsigned int g;

void foo(void)
{
    unsigned int r;

    r = ~ field;                     /* Message 0469 and also 0557 */
    r = ~ p;                         /* Message 0469 and also 0557 */
    r = ~ f;                         /* Message 0469 */
    r = ~ g;                         /* OK           */

}
