Hello,

I'm trying to write my first driver for WinXP using the latest DDK from
MS. I'm having a few problems (understatment).

Mainly I need to access some ports and send the data to a VB app. I
have decided to use the READ_PORT_XXXX and WRITE_PORT_XXXX wrapers from
NTDDK.h. This means I will be writing a kernal-mode driver.

Now I am trying to get the DriverEntry procedure at least entered into
my code. The first time I ran Build I received the following error
bufferoverflowk.lib(gs_support.obj) : error LNK2019: unresolved
external symbol _DriverEntry@8 referenced in function _GsDriverEntry@8

So i added the following to one of the .H files :
extern "C" {
NTSTATUS __stdcall DriverEntry(
PDRIVER_OBJECT DriverObject,
PUNICODE_STRING RegistryPath
);
}

When I run build I get this error:
c:\WINDDK\FLASH_XP_Driver\New_Code.h(21) : error C2059: syntax error :
'string'

Line 21 is the extern "C" { line from above.

Could anyone give me some advice to get the DriverEntry section to
compile without errors?

Thanks.

Mike

For a first driver, avoid C++, take a look at
http://www.microsoft.com/whdc/driver/kernel/KMcode.mspx to see why this can
be a challenge.

The dirty little secret of driver writing, is almost everyone starts with an
existing driver. Consider taking one of the simpler samples from
src\general, make a copy, be sure it can build, then start applying your
changes.

Name the DriverEntry function literally = "DriverEntry". This is like
main().
