PRINTER_NOTIFY_INFO

PRINTER_NOTIFY_INFO_DATA

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.

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;

Members

Type

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

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

Field

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

Reserved

Reserved.

Indicates the job identifier if the Type member specifies JOB_NOTIFY_TYPE. If the Type member specfies 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 following Remarks section.

The NotifyData union can be one of the following members:

Member	Meaning
adwData	An array of two DWORD values. For information fields that use only a single DWORD, the data is in adwData[0]
Data	The following members are contained in the Data structure:

Member	Meaning
cbBuf	Indicates the size, in bytes, of the buffer pointed to by pBuf.
pBuf	Points to a buffer that contains the field's current data.

	adwData[0] specifies the default priority value assigned to each print job.
PRINTER_NOTIFY_FIELD_START_TIME
	adwData[0] specifies the earliest time at which the printer will print a job. (This value is specified in minutes elapsed since 12:00 A.M.)
PRINTER_NOTIFY_FIELD_UNTIL_TIME
