WEC7 DHHalLib (function library)

The DHHalLib provides hardware related functions for Windows Embedded CE 6 and Windows Embedded Compact 7. All the functionality is available from the user mode.

Version numbers

Read DHHalLib version

unsigned long DHHalLibGetVersion()

Return value: unsigned long --> version number (e.g. 0x01040001 for version 1.4.0.1)

BSP version

unsigned long BSPGetVersion()

Return value: unsigned long --> version number (e.g. 0x01040001 for version 1.4.0.1)

Note: The version number information is stored in the following registry key: [HKEY_LOCAL_MACHINE\Ident] dword:"BSPVersionNumber"

Read image version
