IoRegisterInterface and GUID

NTDEV
1

Hi,
I have the following line in AddDevice() :

Status =
IoRegisterDeviceInterface(DeviceObject,(LPGUID)&GUID_CLASS_COMPORT,NULL,&Sym
bolicLinkName);

At link time I get:

pilotewdm.obj : error LNK2001: unresolved external symbol
_GUID_CLASS_COMPORT
objchk_w2K_x86\i386\WDMDriver.sys : fatal error LNK1120: 1 unresolved
externals

what is the lib to link to my driver ?

OK, I had’nt read all the documentation. I forgot to include “initguid.h”
