error LNK2019: unresolved external symbol "long __stdca

[naveenadevi]

Hi,
I'm trying to use some power management features with windowsx xp
and I have visual studio .net 2003 installed.
As per documentation of ACPI, you can
use the power options by including the Powrprof.h file and use the
Powrprof.lib file in your project, which I did, but when I build, it
compiles fine but I get this Link error.. :

error LNK2019: unresolved external symbol "long __stdcall
CallNtPowerInfo rmation(enum POWER_INFORMATI ON_LEVE,void*,u signed
long,void*,unsi gnedlong)"
(?CallNtPowerIn formation@@YGJW 4POWER_INFORMAT ION_LEVEL@@PAXK 1K@Z)
referenced in
function _main
fatal error LNK1120: 1 unresolved externals
The code is as shown below :...
Any Ideas on what I'm missing here... please help...

Thanks,
Regards,
AS.
#include "stdafx.h"

#include <windows.h>
#include <stdio.h>
#include <lmaccess.h>

#include <powrprof.h>
int _tmain(int argc, _TCHAR* argv[])
{
SYSTEM_POWER_CA PABILITIES cap;

NTSTATUS status;
status = CallNtPowerInfo rmation(
SystemPowerCapa bilities,
NULL,
0,
&cap,
sizeof(cap));

return 0;
}

I suspect that you need to link against Powrprof.lib.

I am having the same issue. Powrprof.lib is listed in my IDE to be linked.
Any other ideas?

Thanks.

Your problem is that you didn't put the 'extern "C" {}' around the #include<pawrpr of.h>.
I had the same problem and that fixed it.

Good luck!

with GetProcAddress function.
