NAME

       joystick_update - query joysticks for status changes

SYNOPSIS

       #include <vgajoystick.h>

       int joystick_update(void);

DESCRIPTION

       queries  all  currently opened joysticks for position changes and calls
       the appropriate event handlers.

       A non-zero value is returned if and only if  any  joystick  reported  a
       position change. In more detail the logical and of the return value and
       (1 << joydev) is non-zero if this joystick status changed.

CAVEATS

       This function is only available in ELF  versions  of  svgalib.  Due  to
       backwards  compatibility  issues  it  cannot  be used with shared a.out
       libs.

       and  code  to  glue  it  into  svgalib  by  Michael Weller <eowmob@exp-

       Vojtech Pavlik.
