C++ (Cpp) JSUpdate Examples

Example #1

File: AFXexec2.c Project: sadistech/afx

void check_quit_action() {
	// this is where we loop and check for joystick quit event (buttons 8 and 9);
	
	int i, status;

	const char *device = "/dev/input/js0";
	const char *calib = "/home/spike/.joystick.bak";

	js_data_struct jsd;

	signal(SIGINT, MySignalHandler);

	status = JSInit(&jsd, device, calib, JSFlagNonBlocking);

	if (status != JSSuccess) {
		printf("ERROR with joystick!\n");
		JSClose(&jsd);
		exit(EXIT_FAILURE);
	}

	printf("Initialized joystick: %s\n", jsd.name);
