ID3D11Device::CreateCounter method (d3d11.h)

Create a counter object for measuring GPU performance.

Syntax

HRESULT CreateCounter(
  [in]            const D3D11_COUNTER_DESC *pCounterDesc,
  [out, optional] ID3D11Counter            **ppCounter
);

Parameters

[in] pCounterDesc

Type: const D3D11_COUNTER_DESC*

Pointer to a counter description (see D3D11_COUNTER_DESC).

[out, optional] ppCounter

Type: ID3D11Counter**

Address of a pointer to a counter (see ID3D11Counter).

Return value

Type: HRESULT

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.
