D3DDDIARG_CREATEQUERY structure (d3dumddi.h)

The D3DDDIARG_CREATEQUERY structure identifies a query to create.

Syntax

typedef struct _D3DDDIARG_CREATEQUERY {
  [in]  D3DDDIQUERYTYPE QueryType;
  [out] HANDLE          hQuery;
} D3DDDIARG_CREATEQUERY;

Members

[in] QueryType

A D3DDDIQUERYTYPE-typed value that indicates the query type to create resources for.

[out] hQuery

A handle to the query. The user-mode display driver's CreateQuery function returns this handle to the Microsoft Direct3D runtime.

Remarks

The Direct3D runtime uses the handle that is specified by the hQuery member when the runtime calls:

• The IssueQuery function to process a query.
• The GetQueryData function to retrieve information about the query.
• The DestroyQuery function to destroy the handle.
