Reducing console size

Question

I got a problem with changing console size. This is my code:

BOOL setConsole(int x, int y)
{
hStdin = GetStdHandle(STD_INPUT_HANDLE); 
hStdout = GetStdHandle

Late to the party ...

As far as can be devised from MSDN and a few tests, the screen buffer can't be set smaller than the window's extent or the window's extent made bigger than the screen buffer.

One hack is to shrink the window to a minimal before changing the buffer size :

static void
set_console_size(HANDLE screen_buffer, SHORT width, SHORT height)
{
    assert(screen_buffer != NULL);
    assert(width > 0);
    assert(height > 0);

    COORD const size = { width, height };
    BOOL success;

    SMALL_RECT const minimal_window = { 0, 0, 1, 1 };
    success = SetConsoleWindowInfo(screen_buffer, TRUE, &minimal_window);
    CHECK(success);

    success = SetConsoleScreenBufferSize(screen_buffer, size);
    CHECK(success);

    SMALL_RECT const window = { 0, 0, size.X - 1, size.Y - 1 };
    success = SetConsoleWindowInfo(screen_buffer, TRUE, &window);
    CHECK(success);
}
