glutKeyboardFunc(3GLUT)                             GLUT                             glutKeyboardFunc(3GLUT)



NAME
       glutKeyboardFunc - sets the keyboard callback for the current window.

SYNTAX
       #include <GLUT/glut.h>

       void glutKeyboardFunc(void (*func)(unsigned char key,
                             int x, int y));

ARGUMENTS
       func      The new keyboard callback function.

DESCRIPTION
       glutKeyboardFunc  sets the keyboard callback for the current window.  When a user types into the win-dow, window,
       dow, each key press generating an ASCII character will generate a keyboard callback. The key callback
       parameter is the generated ASCII character. The state of modifier keys such as Shift cannot be deter-mined determined
       mined directly; their only effect will be on the returned ASCII data. The x and y callback parameters
       indicate  the mouse location in window relative coordinates when the key was pressed. When a new win-dow window
       dow is created, no keyboard callback is initially registered, and ASCII key strokes in the window are
       ignored. Passing NULL to glutKeyboardFunc disables the generation of keyboard callbacks.

       During  a  keyboard  callback, glutGetModifiers may be called to determine the state of modifier keys
       when the keystroke generating the callback occurred.

       Use glutSpecialFunc for a means to detect non-ASCII key strokes.
