HIDClass Support Routines

NTDEV
1

Hi all,

I’m trying to write a user mode app that will use the SetupDi functions to
find the device handle to my HID device. except the problem I’m having is I
can’t get my program to link. It’s complaining about the call to
HidD_GetHidGuid() I tried telling to compiler to link to hid.lib,
hidclass.lib and hidparse.lib, none of which seem to resolve the issue… I
know my lib path is pointing to the DDK correctly because it will use the
setupapi.lib fine.

What am I doing wrong?

Thanks!

-Jeff

My psychic powers tell me that you are creating the application in C++
and that the linker is giving you a missing symbol of
_HidD_GetHidGUID@. You need to wrap the #include of
hidsdi.h in an extern “C”, ie

extern “C” {
#include “hidsdi.h”
}

Hid.lib is the lib you need to link against.

Is it a .cpp file? Have you wrapped the include to disable name decoration?

extern “C” {
#include <hidsdi.h>
}

Some of the DDK files have this built-in, but many do not. hidsdi.h
does not.

psychic powers astound me =)
