CEDDK.dll exposes functions typically used by drivers for handling bus address translations, allocating and mapping device memory, setting up direct memory access (DMA) buffers, performing I/O, and so on. You can implement CEDDK.dll to support any bus on your hardware platform.

While you are completing your OAL, implement CEDDK.dll. To implement CEDDK.dll, you can use the default files or you can create your own to support your hardware platform. Many platforms only implement a unique Ddk_bus.c file and link to the other libraries built from the public tree.

The following table shows the location of the CEDDK.dll source code in the %_WINCEROOT%\Public\Common\OAK\Drivers\CEDDK directory.
