Solution 1

The proper way to call the function would be

C++

HRESULT hr = NVGetHWEncodeCaps();
if (FAILED(hr))
{
 // handle error
}
//...

i write your code but it has error:
error: identifier "NVGetHWEncodeCaps" is undefined

int main()
{

HRESULT hr = NVGetHWEncodeCaps();
if (FAILED(hr))
{
printf("failed"+hr);
}
else
printf("ok"+hr);
getch();
return 0;

}
i want to see the output of this function.plz help!

If it's undefined, then you're probably not including the header properly or your function prototype doesn't match what's on the header.
