NAME
       joystick_getnumaxes, joystick_getnumbuttons - query the capabilities of
       a joystick

SYNOPSIS
       #include <vgajoystick.h>

       char joystick_getnumaxes(int joydev);
       char joystick_getnumbuttons(int joydev);

DESCRIPTION
       queries the number of axes (number of continuous ranges which the
       joystick allows to choose from) and buttons. The old version 0.*
       joystick protocol reports 2 axes (x and y) and 4 buttons although the
       actual joystick will usually have less (often two) buttons.

       svgalib supports up to 127 axes and buttons, provided the underlying
       device driver does it.

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.
