\class Joystick
\ingroup device
\brief Class that provides an interface to joysticks and game controllers.
This class adds support for joysticks and other similar game controllers
through game ports, both, on cards and some build-in ports.
This class allows application to access the data from game controllers of
any type (joysticks, gamepads, racing wheels, etc). It provides discovery
of the button configuration and axis layout and reports the status of the
buttons and position of the axis. There is also support for enumerating the
available controllers.
The class also provides two modes - standard and enhanced
Joysticks can be accessed in two modes called standard and enhanced. The
standard mode is for compatibility with the BeBox joysticks and is not
implemented in Haiku. New applications should use the enhanced mode.

\fn status_t BJoystick::Open(const char *portname, bool enhanced)
\brief Open a specific game port.
This method can be used to open the game port specified by the parameter
\c portname amd also allows you to specify whether to use enhanced mode or
not.
This method can be used to open the game port specified by the parameter
\c portname amd also allows you to specify whether to use enhanced mode or
not. The port name can be either an absolute path to the game port device,
or only the device file name.
Enhanced mode adds support for up to 32 buttons per joystick, an indefinite
number of axes and thumb controls, and also allows you to connect multiple
joysticks to a single game port. It provides several methods to determine
the state of a joystick and also a preference application.
Enhanced mode adds support for more than 32 buttons per joystick, and an
unlimited number of axes and thumb controls. To support this, several
functions allow to get information about the device, such as the button
count, the name of each button, and the number and name of the axis.
Enhanced mode also provides a mechanism to determine what joysticks are
available and what types of and how many controls are available on them.
\param portname The name of the game port to be opened.
\param enhanced Specifies whether to use enhanced mode while opening the port.
\return B_BAD_VALUE if portname is null.
B_ERROR if the specified port is unable to open or if portname is not valid.
A positive integer if the port is opened succesfully.
\see CountDevices()
GetDeviceName()
\param portname The name of the game port to be opened.
\param enhanced Specifies whether to use enhanced mode while opening the port.
\return B_BAD_VALUE if portname is null.
\return B_NO_INIT if the object failed to initialize.
\return B_ERROR if the specified port cannot be open.
\return The file descriptor for the port if it is opened succesfully.
