[previous] 0448 [next] [C] Operand of ++/-- must not be a pointer to an object of unknown size.
Constraint violations REFERENCE - ISO:C90-6.3.2.4 (Postfix), ISO:C90-6.3.3.1 (Prefix) Increment and Decrement Operators

This is a constraint error

A pointer cannot be incremented or decremented if the object to which it points is of incomplete type, i.e. an object of unknown size. For example: 


/*PRQA S 410,510,3313,3408,3447,3673 ++*/

extern struct TAG *pc;
extern int (*pa)[];
extern void       *pv;

void foo (void)
{
    ++pc;               /* Message 0448 */
    ++pv;               /* Message 0448 */
    ++pa;               /* Message 0448 */
}
