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.
