KSRESOLUTION structure

Description

The KSRESOLUTION structure specifies granularity and error of a kernel streaming clock.

Members

`Granularity`

Specifies the increment granularity of the clock in 100-nanosecond units, where 1 is the best.

`Error`

Specifies the +/- notification error of the clock in 100-nanosecond units, where 0 is the best, meaning the event notification granularity is as good as the increment granularity.

Remarks

Vendors can supply a structure of type KSRESOLUTION in a KSPROPERTY_CLOCK_RESOLUTION property request.
