TpVersion_t DevGetDriverVersion ( LibTiePieHandle_t  hDevice)

Get the version number of the driver used by the device.

Parameters
[in]hDeviceA device handle identifying the device.
Returns
Driver version number, or zero if no version number is available.
Status values
NOT_SUPPORTED The indicated device does not support reading a driver version or does not require a driver.
INVALID_HANDLE The handle to the device is invalid.
OBJECT_GONE The object indicated by the handle is no longer available.
LIBRARY_NOT_INITIALIZEDThe library is not initialized, see LibInit().
SUCCESS The function executed successfully.
Example
TpVersion_t Version = DevGetDriverVersion( hDevice );
uint16_t wMajor = TPVERSION_MAJOR( Version );
uint16_t wMinor = TPVERSION_MINOR( Version );
