Parameters

flags  QueryDisplayConfigFlags

The type of information to retrieve.

refPathInfoArrayCount  UInt32

The number of elements in the path information table.

The refPathInfoArrayCount parameter value is then used by a subsequent call to the QueryDisplayConfig(QueryDisplayConfigFlags, UInt32, DisplayConfigPathInfo, UInt32, DisplayConfigModeInfo, DisplayConfigTopologyId) function.

This parameter cannot be see .

refModeInfoArrayCount  UInt32

The number of elements in the mode information table.

The refModeInfoArrayCount parameter value is then used by a subsequent call to the QueryDisplayConfig(QueryDisplayConfigFlags, UInt32, DisplayConfigPathInfo, UInt32, DisplayConfigModeInfo, DisplayConfigTopologyId) function.

This parameter cannot be see .
