D3DDDICB_LOCK2FLAGS structure (d3dukmdt.h)

  • Article

D3DDDICB_LOCK2FLAGS is used by the Lock2 kernel function to determine how an allocation is locked.

Unlike Lock, which supported numerous flags, Lock2 has none. The Lock2 arguments allow flags to be specified using this structure, but currently it only has a reserved field to allow for capabilities to added in the future.

Syntax

  union {
    struct {
      UINT Reserved : 32;
    };
    UINT Value;
  };
} D3DDDICB_LOCK2FLAGS;
