Pure C language to set the window size

If you want to change the screen buffer can:

COORD size = {w, h};
HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);

If you only need to change the window size can:

SMALL_RECT rc = {1,1, w, h};
SetConsoleWindowInfo(hOut ,true ,&rc);

Note: The window size can not exceed the buffer size, or modification will fail!

Function modeset(int w,int h):

void modeset(int w,int h) {
//	此函数设置窗口大小为 w*h
	HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
	COORD size = {w, h};
	SetConsoleScreenBufferSize(hOut,size);
	SMALL_RECT rc = {1,1, w, h};
	SetConsoleWindowInfo(hOut ,true ,&rc);
	return;
}

The complete code is:

#include <Windows.h>
void modeset(int w,int h) {
	HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
	COORD size = {w, h};
	SetConsoleScreenBufferSize(hOut,size);
	SMALL_RECT rc = {1,1, w, h};
	SetConsoleWindowInfo(hOut ,true ,&rc);
	system("cls");
	return;
}
int main(){
	modeset(100,50);
	return 0;
}
