#include <conio.h> void textmode(int _mode);
Sets the text mode of the screen. _mode is one of the following:
The text mode which was in effect before the last call to
40-column black and white (on a color screen)
80-column black and white (on a color screen)
The monochrome monitor
80-column, 43- (on EGAs) or 50-row (on VGAs) color
See section _set_screen_lines, for a more versatile method of setting text screen dimensions.
It's not safe to call this function inside static constructors, because conio needs to be initialized, and its initialization is done by a static constructor. Since you don't have any control on the order in which static constructors are called (it's entirely up to the linker), you could have problems.
If you can detect the situation when one of the conio functions is
called for the very first time since program start, you could work
around this problem by calling the
manually (this is the function called by a static constructor).
