The DD_HALINFO structure describes the driver’s supported hardware capabilities. The driver sets and returns all fields of this structure in its DrvGetDirectDrawInfo implementation.

Members

dwSize

Size, in bytes, of the DD_HALINFO structure.

vmiData

VIDEOMEMORYINFO structure that contains video memory information.

ddCaps

DDCAPS structure that contains driver-specific capabilities. The DD_CAPS structure is defined in ddraw.h.

dwMonitorFrequency

Monitor frequency in the current mode.

dwFlags
