NAME

       joystick_close - close a joystick

SYNOPSIS

       #include <vgajoystick.h>

       void joystick_close(int joydev);

DESCRIPTION

       closes the joystick joydev which was opened with joystick_init(3).

       joydev = -1 closes all currently open joystick devices. Note that any calibration data is lost if you close a joystick.

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.

NAME

       joystick_sethandler, joystick_setdefaulthandler - set the joystick event handler.

SYNOPSIS

       #include <vgajoystick.h>
       typedef void (*__joystick_handler) (int event, int number, char value, int joydev);

       void joystick_sethandler(int joydev, __joystick_handler jh);
       void joystick_setdefaulthandler(int joydev);

DESCRIPTION

       By  default,  each call to joystick_init(3) enables the default handler for the opened joystick. This handler maintains a state table which
       can be read by the joystick_getaxis(3), joystick_getbutton(3), joystick_button1|2|3|4(3),  joystick_getb1|2|3|4(3),  joystick_x|y|z(3)  and
       joystick_getx|y|z(3) functions.

       If you define an own handler, the following parameters are passed:

	      event one of the following values:

		     JOY_EVENTBUTTONDOWN a button was pressed.

		     JOY_EVENTBUTTONUP a button was released.

		     JOY_EVENTAXIS the joystick position was changed.

		     All other values are reserved for future use.

	      number identifies the button or axis to which this event belongs.

	      value for axis events the new position in range -128 .. 127.See joystick_getaxis(3) for further comments on the range.

	      joydev identifies the joystick affected (this allows to use one handler for many joysticks).

       joydev = -1 modifies the event handler of all currently open joystick devices.
