- Name textmode - changes the current video mode to newmode
-
- Usage void textmode(int newmode);
-
- Prototype in conio.h
-
- Description textmode selects a specific text mode.
-
- You can give the text mode (the argument mode) by
- using a symbolic constant from the enumeration
- type text_modes (defined in CONIO.H); if you use
- these constants, you must #include <conio.h>
-
- The text_mode type constants, their numeric
- values, and the modes they specify are given in
- the following table.
-
- ------------------------------------------------
- Symbolic Numeric Text mode
- constant value
- ------------------------------------------------
-
- LAST -1 Previous text mode
- BW40 0 Black & white, 40 columns
- C40 1 Color, 40 columns
- BW80 2 Black & white, 80 columns
- C80 3 Color, 80 columns
- MONO 7 Monochrome, 80 columns
- C4350 64 Color, 43 lines/EGA, 50 lines/VGA
-
- When textmode is called, the current window is
- reset to the entire screen, and the current text
- attributes are reset to normal, corresponding to
- a call to normvideo.
-
- Specifying LAST to textmode causes the most-
- recently-selected text mode to be reselected.
- This feature is really only useful when you want
- to return to text mode after using a graphics
- mode.
-
- Return value None
