D3DKMT_PRESENT_DISPLAY_ONLY_FLAGS structure

Indicates how a kernel mode display-only driver (KMDOD) is to perform a present operation.

Syntax


typedef struct _D3DKMT_PRESENT_DISPLAY_ONLY_FLAGS {
  union {
    struct {
      UINT Rotate  :1;
      UINT Reserved  :31;
    };
    UINT   Value;
  };
} D3DKMT_PRESENT_DISPLAY_ONLY_FLAGS;

Members

Rotate

[in] A UINT value that specifies whether to rotate the presentation data to match the current orientation of the screen during the presentation bit-block transfer (bitblt). The current orientation of the screen is set in the Rotation member of a D3DKMDT_VIDPN_PRESENT_PATH_TRANSFORMATION structure, which is set in the ContentTransformation member of the D3DKMDT_VIDPN_PRESENT_PATH structure for the video present path.

The KMDOD should rotate the data only if the Rotate bit-field flag is set. Even if the KMDOD determines that the current orientation of the screen is rotated from the presentation data and Rotate is not set, the KMDOD should not rotate the data.

Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

Reserved

[in] This member is reserved and should be set to zero.

Setting this member to zero is equivalent to setting the remaining 31 bits (0xFFFFFFFF) of the 32-bit Value member to zeros.

Value

A member in the union that D3DKMT_PRESENT_DISPLAY_ONLY_FLAGS contains that can hold a 32-bit value that identifies the type of present operation to perform.
