EFI_EDID_OVERRIDE_PROTOCOL_GET_EDID

typedef EFI_STATUS(EFIAPI * EFI_EDID_OVERRIDE_PROTOCOL_GET_EDID) (IN EFI_EDID_OVERRIDE_PROTOCOL *This, IN EFI_HANDLE *ChildHandle, OUT UINT32 *Attributes, OUT UINTN *EdidSize, OUT UINT8 **Edid)

Returns policy information and potentially a replacement EDID for the specified video output device.

Parameters

This	The EFI_EDID_OVERRIDE_PROTOCOL instance.
ChildHandle	A child handle produced by the Graphics Output EFI driver that represents a video output device.
Attributes	The attributes associated with ChildHandle video output device.
EdidSize	A pointer to the size, in bytes, of the Edid buffer.
Edid	A pointer to callee allocated buffer that contains the EDID that should be used for ChildHandle. A value of NULL represents no EDID override for ChildHandle.

Return values

EFI_SUCCESS	Valid overrides returned for ChildHandle.
EFI_UNSUPPORTED	ChildHandle has no overrides.
