Structure Members

typedef struct {

        COMMON_DATA;

        uint32  first;          /* first valuator reported      */
        uint32  count;          /* number reported              */
        sint32  value[32];      /* absolute/relative values     */

} gii_val_event;

A valuator may be either absolute or relative, like pointer motion events.

To interpret the numbers, query valuator device info with GII_CMDCODE_GETVALINFO.
