register variables aren't that free when compared to auto variables and they should be only be sparsely used when that is really needed. I felt for the above code is not needed. Anyway its up to the programmer to decide and the compiler is not going to complain about this.

Its going to allocate if that can find one, else its going to be an auto variable anyway

NAME
glutIgnoreKeyRepeat - determines if auto repeat keystrokes are reported to the current window SYNTAX
#include <GLUT/glut.h> void glutIgnoreKeyRepeat(int ignore); ARGUMENTS
ignore Non-zero indicates auto repeat keystrokes should not be reported by the keyboard and special callbacks; zero indicates that auto repeat keystrokes will be reported. DESCRIPTION
glutIgnoreKeyRepeat determines if auto repeat keystrokes are reported to the current window. The ignore auto repeat state of a window can be queried with glutDeviceGet(GLUT_DEVICE_IGNORE_KEY_REPEAT). Ignoring auto repeated keystrokes is generally done in conjunction with using the glutKeyboardUpFunc and glutSpecialUpFunc callbacks to repeat key releases. If you do not ignore auto repeated keystrokes, your GLUT application will experience repeated release/press call- backs. Games using the keyboard will typically want to ignore key repeat. GLUT IMPLEMENTATION NOTES FOR X11 X11 sends KeyPress events repeatedly when the window system's global auto repeat is enabled. glutIgnoreKeyRepeat can prevent these auto repeated keystrokes from being reported as keyboard or special callbacks, but there is still some minimal overhead by the X server to con- tinually stream KeyPress events to the GLUT application. The glutSetKeyRepeat routine can be used to actually disable the global sending of auto repeated KeyPress events. Note that glutSetKeyRepeat affects the global window system auto repeat state so other applications will not auto repeat if you disable auto repeat globally through glutSetKeyRepeat. SEE ALSO
