glutGetModifiers  -  returns  the  modifier key state when
       certain callbacks were generated.

SYNTAX

       int glutGetModifiers(void);

DESCRIPTION

       glutGetModifiers returns the modifier  key  state  at  the
       time  the  input  event  for a keyboard, special, or mouse
       callback is generated.  This routine may  only  be  called
       while a keyboard, special, or mouse callback is being han-
       dled. The window system is permitted to  intercept  window
       system  defined  modifier key strokes or mouse buttons, in
       which case, no  GLUT  callback  will  be  generated.  This
       interception  will  be  independent of use of glutGetModi-
       fiers.

       The bitmask components of the returned integer value are:

       GLUT_ACTIVE_SHIFT
               Set if the Shift modifier or Caps Lock is  active.

       GLUT_ACTIVE_CTRL
               Set if the Ctrl modifier is active.

       GLUT_ACTIVE_ALT
               Set if the Alt modifier is active.
