Remarks

Implement this GWES-layer function as part of porting native device drivers. This function is declared in the Battery.h header file.

The syntax for this function is different in Windows CE version 2.12 than in previous versions of the operating system. This function now uses the SYSTEM_POWER_STATUS_EX2 structure instead of the BATTERY_STATUS structure to return the battery status. The new structure contains additional fields to support batteries that can report complex status information. If you are writing a battery driver for a previous version of Windows CE, you should use the following definition of the function BatteryDrvrGetStatus:

Syntax for Windows CE 2.11 and earlier

BOOL BatteryDrvrGetStatus( PBATTERY_STATUS pSystemPowerStatusEx );

Parameters

pSystemPowerStatusEx: Pointer to the buffer in which the battery status information is to be returned.
