Fields

cb
Length of this data structure
Input parameter to VioGetMode. Length specifies the length of the data structure in bytes, including length. The value specified on input controls the amount of mode data returned.
The minimum structure size required is two bytes. The length is modified on output.
fbType
Bit mask of mode being set.
Mode characteristics bit mask:
Bit Description
7-4 Reserved
3 0 = VGA BIOS compatible modes
1 = Native mode
2 0 = Enable color burst
1 = Disable color burst
1 0 = Text mode
1 = Graphics mode
0 0 = Monochrome compatible mode
1 = Other
color
Number of colors.
Number of colors defined as a power of 2. This is equivalent to the number of color bits that define the color, for example:
Value Definition
0 Monochrome
1 2 colors
2 4 colors
4 16 colors
8 256 colors
16 64K colors
24 16M colors
col
The number of text columns.
row
The number of text rows.
hres
Horizontal resolution; the number of pel columns.
vres
Vertical resolution, the number of pel rows.
fmt_ID
Attribute format.
The format of the attributes.
attrib
Number of attributes.
The number of attributes in a character cell.
resv
Reserved.
buf_addr
Video aperture address.
The physical address of the physical display aperture. This may be zero for emulated video hardware.
buf_length
Video aperture length.
The length of the physical display aperture.
full_length
Video state full save length.
The size of the buffer required for a full save of the video state.
partial_length
Video state partial save length.
The size of the buffer required for a partial (pop-up) save of the video state.
ext_data_addr
Extra data address.
The virtual address of an extended mode data structure or zero (if none). The format of the extended mode data structure is determined by the device driver and is unknown to OS/2.
