PRINTER_NOTIFY_INFO info  Overview  Group

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.

typedef struct _PRINTER_NOTIFY_INFO { 

    DWORD  Version; 

    DWORD  Flags; 

    DWORD  Count; 

    PRINTER_NOTIFY_INFO_DATA  aData[1]; 

} PRINTER_NOTIFY_INFO; 

 

Members

Version

Specifies the version of this structure. Set this member to 2.

Flags

Contains a bit flag to indicate 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

Specifies 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 occured, 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.
