D3D10DDI_COUNTER_INFO structure (d3d10umddi.h)
The D3D10DDI_COUNTER_INFO structure describes information to manipulate counters.
Syntax
typedef struct D3D10DDI_COUNTER_INFO {
[out] D3D10DDI_QUERY LastDeviceDependentCounter;
[out] UINT NumSimultaneousCounters;
[out] UINT8 NumDetectableParallelUnits;
} D3D10DDI_COUNTER_INFO;
Members
[out] LastDeviceDependentCounter
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).
[out] NumSimultaneousCounters
The number of simultaneously active counters that the driver supports.
[out] NumDetectableParallelUnits
The number of detectable parallel units that the counters can identify. Valid values are from 1 through 4.
