There's no example, anyway it's quite simple:

You have to write a DLL which exports a function which complies with this
definition:

typedef BOOL (*PFN_UIENTRYPOINT)(
LPVOID lpInBuffer,
DWORD nInBufferSize,
LPVOID lpOutBuffer,
DWORD nOutBufferSize,
PDWORD pBytesReturned
);

For example, suppose you write kmsgbox.dll which exports the following:

extern "C" BOOL KMessageBox(
LPVOID lpInBuffer,
DWORD nInBufferSize,
LPVOID lpOutBuffer,
DWORD nOutBufferSize,
PDWORD pBytesReturned
)
{
return (BOOL)MessageBox(NULL,(LPCTSTR)lpInBuffer,_T("TEST"),MB_OK);
}

Then from kernel mode you can call:

CeCallUserProc(_T("kmsgbox.dll"),_T("KMessageBox"),...);

To show the Message Box;

Notice that, although the docs do not specify it:

* you can not pass a NULL lpInBuffer parameter to CeCallUserProc
** nInBufferSize parameter can not be greater than nOutBufferSize
