1/6/2010
This structure contains information about the GPS Intermediate Driver and GPS hardware used by the GPS Intermediate Driver.
To retrieve the data represented by this structure, call GPSGetDeviceState.
Syntax
typedef struct _GPS_DEVICE {
DWORD dwVersion;
DWORD dwSize;
DWORD dwServiceState;
DWORD dwDeviceState;
FILETIME ftLastDataReceived;
WCHAR szGPSDriverPrefix[GPS_MAX_PREFIX_NAME];

} *PGPS_DEVICE, GPS_DEVICE;
Members
- dwVersion
Version of the GPS Intermediate Driver expected by the application. Must be set before the structure is passed to GPSGetDeviceState.
- dwSize
Size of the structure, in bytes. Must be set before the structure is passed to GPSGetDeviceState.
- dwServiceState
State of the GPS Intermediate Driver. Contains one of the SERVICE_STATE values defined IOCTL_SERVICE_STATUS.
- dwDeviceState
State of the driver controlling the GPS hardware. Contains one of the SERVICE_STATE values defined in IOCTL_SERVICE_STATUS.
- ftLastDataReceived
Most recent time the GPS Intermediate Driver received information from the GPS hardware. This time is based on UTC according to the local system clock, not the clock information used by GPS satellites.
- szGPSDriverPrefix
Prefix string used to open the GPS hardware. This entry is defined by the CommPort registry entry for hardware that connects through a serial (or virtual serial) interface. This entry is empty when the GPS Intermediate Driver reads information from static files. For more information about GPS hardware registry settings, see GPS Intermediate Driver GPS Hardware Registry Settings.
szGPSMultiplexPrefix
Prefix string used to open the GPS Intermediate Driver multiplexer. This entry is defined by the DriverInterface registry entry in the Multiplexer key. For more information about multiplexer registry settings, see GPS Intermediate Driver Multiplexer Registry Settings.For more information about accessing data using the GPS Intermediate Driver multiplexer, see Accessing Raw GPS Data.
- szGPSFriendlyName
Friendly name of the GPS hardware currently used by the GPS Intermediate Driver. This entry is defined by the FriendlyName registry entry. For more information about this registry entry, see GPS Intermediate Driver Input Source Registry Settings.
