joystick_getnumaxes3
Query the capabilities of a joystick
Usage
#include <vgajoystick.h>
char joystick_getnumaxes(int joydev);
char joystick_getnumbuttons(int joydev);
Overview
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.
Releases
Unchanged in 5 releases since Debian 3.1 (Sarge).
