// Auto-fullscreen routine for console windows by Nathan Dunn, 2005// Include stuff for manipulating windows #include <windows.h>// The length of our buffer to hold the window title#define CONSOLE_TITLE_LENGTH 200// Entry pointint main(){	// Buffer to hold the original title	char szOldConsoleTitle[CONSOLE_TITLE_LENGTH] = {0};	// The new title of the window.

SetConsoleTitle(szOldConsoleTitle);	// Now we send the ALT+ENTER message to the window. We	// send SendMessage the handle to the window, the message	// that we are pressing the ALT key and another key, that	// that other key is the ENTER key, and verification that	// the ALT key is indeed down. The window receives this and	// says "Oh, hey! I need to go fullscreen! Well, let's do it	// then." All that is handled by the console window itself,	// and you don't have to worry about it.
