PRINTER_NOTIFY_INFO_DATA structure

The PRINTER_NOTIFY_INFO_DATA structure identifies a job or printer information field and provides the current data for that field.

The FindNextPrinterChangeNotification function returns a PRINTER_NOTIFY_INFO structure, which contains an array of PRINTER_NOTIFY_INFO_DATA structures.

Syntax

typedef struct _PRINTER_NOTIFY_INFO_DATA {
  WORD  Type;
  WORD  Field;
  DWORD Reserved;
  DWORD Id;
  union {
    DWORD  adwData[2];
    struct {
      DWORD  cbBuf;
      LPVOID pBuf;
    } Data;
  } NotifyData;
} PRINTER_NOTIFY_INFO_DATA, *PPRINTER_NOTIFY_INFO_DATA; ;

Members

Type

Indicates the type of information provided. This member can be one of the following values.

Value Meaning
JOB_NOTIFY_TYPE
0x01
Indicates that the Field member specifies a JOB_NOTIFY_FIELD_* constant.
PRINTER_NOTIFY_TYPE
0x00
Indicates that the Field member specifies a PRINTER_NOTIFY_FIELD_* constant.

Field

Indicates the field that changed. For a list of possible values, see the Remarks section.

Reserved

Reserved.

Id

Indicates the job identifier if the Type member specifies JOB_NOTIFY_TYPE. If the Type member specifies PRINTER_NOTIFY_TYPE, this member is undefined.

NotifyData

A union of data information based on the Type and Field members. For a description of the type of data associated with each field, see the Remarks section.

adwData[2]

An array of two DWORD values. For information fields that use only a single DWORD, the data is in adwData [0].

Data

cbBuf

Indicates the size, in bytes, of the buffer pointed to by pBuf.

pBuf

Pointer to a buffer that contains the field's current data.
