D3D10DDI_COUNTER_INFO structure

The D3D10DDI_COUNTER_INFO structure describes information to manipulate counters.

Syntax

typedef struct D3D10DDI_COUNTER_INFO {
  D3D10DDI_QUERY LastDeviceDependentCounter;
  UINT           NumSimultaneousCounters;
  UINT8          NumDetectableParallelUnits;
};

Members

LastDeviceDependentCounter

[out] A D3D10DDI_QUERY-typed value that identifies the largest device-dependent counter identifier that the device supports. If none are supported, the user-mode display driver must set the value to 0; otherwise, the driver sets the value to greater than or equal to D3D10DDI_COUNTER_DEVICE_DEPENDENT_0 (0x40000000).

NumSimultaneousCounters

[out] The number of simultaneously active counters that the driver supports.

NumDetectableParallelUnits

[out] The number of detectable parallel units that the counters can identify. Valid values are from 1 through 4.
