### QUERYTUPLE

This structure is used in the GreEscape DEVESC_QUERYSIZE call. It associates the type of property you are querying (ulProperty) and the kind of query you will do (DJP_ALL or DJP_CURRENT).

    typedef struct _QUERYTUPLE {

      ULONG     ulProperty;  /*  Identifies specific job property. */

      LONG      lType;       /*  Property type. */

    } QUERYTUPLE;

    typedef   QUERYTUPLE   * PQUERYTUPLE ;
