Create a counter object for measuring GPU performance.
HRESULT CreateCounter( [in] const D3D11_COUNTER_DESC *pCounterDesc, [out, optional] ID3D11Counter **ppCounter );
- pCounterDesc [in]
Type: const D3D11_COUNTER_DESC*
Pointer to a counter description (see D3D11_COUNTER_DESC).
- ppCounter [out, optional]
Address of a pointer to a counter (see ID3D11Counter).
If this function succeeds, it will return S_OK. If it fails, possible return values are: S_FALSE, E_OUTOFMEMORY, DXGI_ERROR_UNSUPPORTED, DXGI_ERROR_NONEXCLUSIVE, or E_INVALIDARG.
DXGI_ERROR_UNSUPPORTED is returned whenever the application requests to create a well-known counter, but the current device does not support it.
DXGI_ERROR_NONEXCLUSIVE indicates that another device object is currently using the counters, so they cannot be used by this device at the moment.
E_INVALIDARG is returned whenever an out-of-range well-known or device-dependent counter is requested, or when the simulataneously active counters have been exhausted.
