Setting the Cursor Position in a Win32 Console Application

How can I set the cursor position in a Win32 Console application? Preferably, I would like to avoid making a handle and using the Windows Console Functions. (I spent all morning running down that dark alley; it creates more problems than it solves.) I seem to recall doing this relatively simply when I was in college using stdio, but I can't find any examples of how to do it now. Any thoughts or suggestions would be greatly appreciated. Thanks.

Additional Details

Here is what I am now trying to do:

COORD pos = {x, y};
HANDLE hConsole_c = CreateConsoleScreenBuffer( GENERIC_READ | GENERIC_WRITE, 0, NULL, CONSOLE_TEXTMODE_BUFFER, NULL );
char * str = "Some Text\r\n";
DWDORD len = strlen(str);

SetConsoleCursorPosition(hConsole_c, pos);
WriteConsole(hConsole_c, str, len, &dwBytesWritten, NULL);
CloseHandle(hConsole_c)

The text string str is never sent to the screen. Is there something else that I should be doing? Thanks.

Using the console functions, you'd use SetConsoleCursorPosition. Without them (or at least not using them directly), you could use something like gotoxy in the ncurses library.

Edit: a wrapper for it is pretty trivial:

// Untested, but simple enough it should at least be close to reality...
void gotoxy(int x, int y) { 
    COORD pos = {x, y};
    HANDLE output = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleCursorPosition(output, pos);
}
