D3D10_DDI_QUERY_DATA_TIMESTAMP_DISJOINT structure

Description

The D3D10_DDI_QUERY_DATA_TIMESTAMP_DISJOINT structure describes timestamp-disjoint information that is used in a call to the CreateQuery(D3D10) function to create a D3D10DDI_QUERY_TIMESTAMPDISJOINT query type and in a call to the QueryGetData function to return information about the query.

Members

`Frequency`

The frequency, in Hz, of the timestamp clock.

`Disjoint`

A BOOL value that indicates whether something caused the timestamp counter to become discontinuous or disjoint. This value is TRUE if the values from TIMESTAMP queries cannot be guaranteed to be continuous throughout the duration of the D3D10DDI_QUERY_TIMESTAMPDISJOINT query. Otherwise, this value should be FALSE.

Remarks

The driver associates a D3D10_DDI_QUERY_DATA_TIMESTAMP_DISJOINT structure with the D3D10DDI_QUERY_TIMESTAMPDISJOINT query type value from the D3D10DDI_QUERY enumeration.
