GNSS_EVENT_2 structure (gnssdriver.h)

The GNSS_EVENT_2 structure defines the information required for a GNSS event.

Syntax

typedef struct {
  ULONG           Size;
  ULONG           Version;
  GNSS_EVENT_TYPE EventType;
  ULONG           EventDataSize;

Members

Size

Structure size.

Version

Version number.

EventType

Event type.

Depending on the event type, a specific data element of the union will be filled.

EventDataSize

The size of the event data union contained in this event.

The GNSS driver must fill in appropriate size to avoid excessive data-copy between the layers. The GNSS adapter will access only the initial bytes of the event data, as specified by this element.

Unused[512]

Unused.

FixData

This structure is filled if EventType is GNSS_Fix_Available.

FixData2

AgnssRequest

This structure is filled if EventType is GNSS_Require_Agnss.

NiRequest

This structure is filled if EventType is GNSS_Event_Ni.

ErrorInformation

This structure is filled if EventType is GNSS_Error.

NmeaData

This structure is filled if EventType is GNSS_Event_NmeaData.

GeofenceAlertData

This structure is filled if EventType is GNSS_Event_GeofenceAlertData.

BreadcrumbAlertData

This structure contains alert information for when the breadcrumb buffer has reached a level where OS read operations should be performed.

GeofencesTrackingStatus

This structure is filled if EventType is GNSS_Event_GeofencesTrackingStatus.

DriverRequestData

This structure is filled if EventType is GNSS_Event_DriverRequest.

CustomData[ANYSIZE_ARRAY]

Custom data field.
