Description
Initialize Graphics Display Device. If not already in graphics mode save
current mode of display device, so it can be restored by fg_term. Put
display device into its graphics mode. Set the current display page to
page 0. Store the characteristics of the display device into the global
variables. On output fg.display is set to the return value, fg.activepage
and fg_displaypage are set to 0. Page 0 is set to FG_BLACK.
Return Value
FG_XXXX Display type that was opened. FG_NULL (0) if failure.
fg_init_all() will attempt to determine the type of display graphics
that is available and open that display device. The
environment variable FG_DISPLAY=XXXXX will override.
The environment variable override will be primarily
useful for non-standard clone boards, or for boards
that emulate multiple boards. fg_init_all is obsolete
but still exists for backward compatibility, use
fg_init for new programs. fg_init_all may not exist in
future releases.
fg_init_cga() will assume that the graphics device is a CGA board and
put it in 640 x 200 x 2 color mode (mode 0x6).
fg_init_cgamedres() will assume that the graphics device is a CGA board
and put it in 320 x 200 x 4 color mode (mode 0x4).
fg_init_egacolor() will assume that the graphics device is a EGA board
with a IBM color monitor (not enhanced color monitor)
and put it into 640 x 200 x 16 color mode (mode 0xE).
fg_init_egaecd() will assume that the graphics device is a EGA board
with a enhanced color monitor and put it into 640 x 350
x 16 color mode (mode 0x10).
fg_init_egamono() will assume that the graphics device is a EGA board
with a IBM monochrome monitor and put it into 640 x 350
x 4 color mode (mode 0xF).
fg_init_egalowres() will assume that the graphics device is a EGA board
with a IBM color monitor and put it into 320 x 200 x 16
color mode (mode 0xD).
fg_init_evgahires() will assume that the graphics device is a Everex
EVGA board with a multifrequency monitor and put it
into 800 x 600 x 16 color mode (mode 0x70).
fg_init_herc() will assume that the graphics device is a Hercules
board. It will determine if there are 1 or 2 pages
available and put it into 720 x 348 x 2 color mode.
fg_init_null() is the bit-bucket graphics device. It always returns
FG_NULL.
fg_init_orchidprohires() will assume the the graphics device is a
Orchid Prodesigner VGA board and put it into 800 x 600
x 16 color mode (mode 0x29).
fg_init_paradisehires() will assume that the graphics device is a
Paradise VGA board and put it into 800 x 600 x 16 color
mode (mode 0x58).
fg_init_toshiba() will assume that the graphics device is a Toshiba
3100 and put it into 640 x 400 x 2 color mode (mode
0x74).
fg_init_tridenthires() will assume that the graphics device is a
Trident VGA board and put it into 800 x 600 x 16 color
mode (mode 0x5B).
fg_init_vegavgahires() will assume that the graphics device is a Video
7 VEGA VGA board and put it into 800 x 600 x 16 color
mode (mode 0x62).
fg_init_vesa6a() will assume that the graphics device is a VESA
compatible VGA board and put it into 800 x 600 x 16
color mode (mode 0x6A).
fg_init_vesa2() will assume that the graphics device is a VESA
compatible VGA board and put it into 800 x 600 x 16
color mode (mode 0x102).
fg_init_vga11() will assume that the graphics device is a VGA board and
put it into 640 x 480 x 2 color mode (mode 0x11).
fg_init_vga12() will assume that the graphics device is a VGA board and
put it into 640 x 480 x 16 color mode (mode 0x12).
fg_init_vga13() will assume that the graphics device is a VGA board and
put it into 320 x 200 x 256 color mode (mode 0x13).
fg_init_8514a() will assume that the graphics device is an IBM 8514A
and put it into graphics mode.
