Consio is a small console library for Windows. I created it, so I can make small textbased menus and catch single keystrokes and not always use Tk for creating user interfaces. It's also handy for asking passwords from user and not echo them back to the screen.

The library is written in C and has been compiled with Cygwin tools under Cygwin environment using MinGW libraries and headers (so there are no dependencies to the Cygwin).

The source code and binary are available here: [http://www.iki.fi/mjk/files/Consio.zip].

The whole package is released under the MIT license.

Here's a screenshot:

The library is pretty skimpy (well, it's version 0.1 at the moment, so don't expect too much), but it already implements the following commands:

 Consio::clrscr

   Clears screen (console buffer).

 Consio::gotoxy x y

   Sets a new cursor location to (x;y).

 Consio::getch

   Waits for single key press.

 Consio::getche

   Waits for single key press and echoes it back to the console.

 Consio::putch chr

   Inserts a character to the cursor location.

 Consio::kbhit

   checks if there are any keystokes waiting in the input buffer.
   This function doesn't block or remove anything from the buffer.
   The function will return 1 if there are keystrokes waiting in
   the input buffer. Otherwise returns 0.

 Consio::textattr foregroung background

   Sets foreground and background color. Available color attributes
   for both foreground and background color are:
   
   black blue green cyan red magenta brown lightgray darkgray
   lightblue lightgreen lightcyan lightred lightmagenta yellow white

 Consio::cputs ?-nonewline? string

   Prints string to standard output. If -nonewline is specified, then
   then the newline will not be printed at the end of the line.

 Consio::cgets

   Reads keystrokes from the console until Enter key is pressed. Linefeed
   of newline characters are not included in the result.

 Consio::cgetse

   Reads keystrokes from the console and echoes them back until
   the Enter key is pressed. Linefeed or newline characters are not
   included in the results.

At the moment, this library has been tested only under Windows XP. All feedback is welcome and I would appreciate it greatly if people would tell me, how the library works under different flavors of Windows. The feedback can be appended to this page or sent directly to me (e-mail address is included in the package).
