VIDEO_MODE structure (ntddvdeo.h)

  • Article

The VIDEO_MODE structure contains the requested VGA mode that an adapter should set. This structure is used in conjunction with IOCTL_VIDEO_SET_CURRENT_MODE.

Syntax

typedef struct _VIDEO_MODE {
  ULONG RequestedMode;
} VIDEO_MODE, *PVIDEO_MODE;

Members

RequestedMode

Is the mode that the miniport driver should set if possible. In addition, the two high-order bits can be set to request special behavior from the miniport driver as follows:

VIDEO_MODE_ZERO_MEMORY

Indicates that the miniport driver should zero the video memory in conjunction with the mode set.

VIDEO_MODE_MAP_MEM_LINEAR

Indicates that the miniport driver should map the video memory in a linear fashion if the adapter supports such an operation.
