PRINTER_NOTIFY_INFO structure

The PRINTER_NOTIFY_INFO structure contains printer information returned by the FindNextPrinterChangeNotification function. The function returns this information after a wait operation on a printer change notification object has been satisfied.

Syntax


typedef struct _PRINTER_NOTIFY_INFO {
  DWORD                    Version;
  DWORD                    Flags;
  DWORD                    Count;
  PRINTER_NOTIFY_INFO_DATA aData[1];
} PRINTER_NOTIFY_INFO, *PPRINTER_NOTIFY_INFO;

Members

Version

The version of this structure. Set this member to 2.

Flags

A bit flag that indicates the state of the notification structure. If the PRINTER_NOTIFY_INFO_DISCARDED bit is set, it indicates that some notifications had to be discarded.

Count

The number of PRINTER_NOTIFY_INFO_DATA elements in the aData array.

aData

An array of PRINTER_NOTIFY_INFO_DATA structures. Each element of the array identifies a single job or printer information field, and provides the current data for that field.

Remarks

If the Flags member has the PRINTER_NOTIFY_INFO_DISCARDED bit set, this indicates that an overflow or error occurred, and notifications may have been lost. In this case, you must call FindNextPrinterChangeNotification and specify the PRINTER_NOTIFY_OPTIONS_REFRESH flag to retrieve all current information. Until you request this refresh operation, the system will not send additional notifications for this change notification object.
