Is a wildcard for more than one character?
It depends on where you are using it. Back in the DOS days, a * meant multiple characters and a ? meant one character. I've seen software that says to use *, ?, and % for wildcards, but they were all for multiple characters. So it really depends on what you are using. Not everything supports a single wildcard.
What is the return value of getch?

How get input form keyboard?
Retrieving keyboard input depends partly upon whether you're writing a console or graphical application. If you're writing a console application, you have the following functions available: - sscanf() in the stdio.h header - getchar() in the stdio.h header - getch() in conio.h and curses.h (plus kbhit() if it's available) For Win32 applications, which are event-driven, you'll want to intercept the WM_CHAR event that's passed to your window handler (WndProc). The wParam parameter will contain the character on the keyboard that's pressed. For other APIs, you'll want to check the documentation, or look on the Web for tutorials describing how to get keyboard input using whichever API you're using.

I'm using ubuntu 8.04.1 and when you try pushing esc at the grub prompt to change your password it continue and loads up what do you do?
This is usually caused by using a USB keyboard. The BIOS knows how to use a USB keyboard, and so does Linux. But GRUB can only recognize keyboard inputs from older types of keyboards, like the type that plugs into a PS/2 port. All you need to do is enter your BIOS and enable "Legacy USB" or "USB keyboard emulation." This will allow the keyboard to be used during the initial booting phase, before Linux starts.
