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

I modified the code provided by 'Software_Designer' on Oct 15' 12 and created a command line utility to set the console size and scroll buffers.

I compiled it using DEV C++ (http://www.bloodshed.net/devcpp.html).

An executable is included in https://sourceforge.net/projects/wa2l-wintools/. I hope this helps.

    }    

    SetWindow(width,height,wbuffer,hbuffer);
    return 0;
