VIO colour register

Type

USHORT  cb
USHORT  type
USHORT  firstcolorreg
USHORT  numcolorregs
PCH     colorregaddr

C Declaration Method

typedef struct

Fields

cb

Length of the structure in bytes, including length. The maximum valid value is 12.

type

Request type = 3, get color registers.

Request type 3 for color registers.

firstcolorreg

First color register.

The first color register to get in the color register sequence. It must be specified in the range 0 through 255. The color registers are returned in sequential order.

numcolorregs

Number of color registers to get.

The number of color registers to get; must be specified in the range 1 through 256.

colorregaddr

Area where the color registers are returned.

The far address of a data area where the color registers are returned. The size of the data area must be three bytes times the number of color registers to get. The format of each entry returned is as follows:

Byte 1 Red value

Byte 2 Green value

Byte 3 Blue value
