D3D10DDI_COUNTER_INFO structure

Description

The D3D10DDI_COUNTER_INFO structure describes information to manipulate counters.

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.
