typedef _GGZModule GGZModule
Contains information about a single module. A game module, on the
client, is an executable designed to play a game. Each game type
may have many modules that play it.
typedef _GGZGame GGZGame

Enumeration Type Documentation
enum GGZGameEvent
A GGZGameEvent is an event associated with the game, that is triggered
by a communication from the server or from the game. When a game event
occurs, the associated event handle will be called, and will be passed
the event data (a void*) along with the (optional) user data. All game
events apply to the current game. Game events are usually triggered by
calling ggzcore_server_read_data or ggzcore_game_read_data.
See also:
ggzcore_game_add_event_hook
ggzcore_server_read_data
Enumeration values:
GGZ_GAME_LAUNCHED
A game was launched by the player (you). After this the core
client should call ggzcore_game_get_control_fd, monitor the
socket that function returns, and call ggzcore_game_read_data
when there is data pending. This event is triggered inside of
ggzcore_game_launch.
Parameters:
data NULL
See also:
ggzcore_game_launch
GGZ_GAME_LAUNCH_FAIL
Your game launch has failed. Triggered instead of
GGZ_GAME_LAUNCHED when there’s a failure somewhere.
Parameters:
data NULL
See also:
GGZ_GAME_LAUNCHED
GGZ_GAME_NEGOTIATED
Negotiation with server was successful. This should happen some
time after the launch succeeds. The core client need do nothing
at this point.
Parameters:
data NULL
GGZ_GAME_NEGOTIATE_FAIL
Negotiation was not successful, game launch failed.
Todo
Currently this can’t actually happen...
GGZ_GAME_PLAYING
Game reached the ’playing’ state. When this happens the core
client should call ggzcore_room_launch_table or
ggzcore_room_join_table to finalize the game join.
Parameters:
data NULL
enum GGZHookReturn
GGZ Hook function return types
Enumeration values:
GGZ_HOOK_OK
Success!
GGZ_HOOK_REMOVE
Remove this hook immediately.
GGZ_HOOK_ERROR
A localized error.
GGZ_HOOK_CRISIS
A major error; stop processing the event.
enum GGZLoginType
This controls the type of login a user chooses. A different value will
require different information to be sent to the server.
Enumeration values:
GGZ_LOGIN
Standard login; uname and correct passwd needed.
GGZ_LOGIN_GUEST
Guest login; only a uname is required.
GGZ_LOGIN_NEW
New user login; only a uname is required. Password will be
assigned by the server (but can be passed along).
enum GGZModuleEnvironment
The environment a game frontend expects.
Core clients should offer those game modules which fit their own
environment.
Enumeration values:
GGZ_ENVIRONMENT_PASSIVE
No GUI, no interaction with user
GGZ_ENVIRONMENT_CONSOLE
Text console
GGZ_ENVIRONMENT_FRAMEBUFFER
VESA or framebuffer
GGZ_ENVIRONMENT_XWINDOW
X11 windowed mode (default)
GGZ_ENVIRONMENT_XFULLSCREEN

enum GGZOptionFlags
Enumeration values:
GGZ_OPT_MODULES
Load the default configuration file (unused).
GGZ_OPT_THREADED_IO
Load the game module list.
GGZ_OPT_EMBEDDED
Provide multi-threaded network IO (unused).
GGZ_OPT_RECONNECT
Reconnect automatically after connection loss.
enum GGZRoomEvent
A GGZRoomEvent is an event associated with the room, that is triggered
by a communication from the server. When a room event occurs, the
associated event handler will be called, and will be passed the event
data (a void*), along with the (optional) user data. All room events
apply to the current room unless a room number is given. Room events
are almost always triggered by calling ggzcore_server_read_data.
See also:
ggzcore_room_add_event_hook
ggzcore_server_read_data
Enumeration values:
GGZ_PLAYER_LIST
The list of players in a room has arrived.
Parameters:

enum GGZServerEvent
A GGZServerEvent is an event triggered by a communication from the
server. Each time an event occurs, the associated event handler will be
called, and will be passed the event data (a void*). Most events are
generated as a result of ggzcore_server_read_data.
See also:
ggzcore_server_add_event_hook
Enumeration values:
GGZ_CONNECTED
We have just made a connection to the server. After this point
the server’s socket should be accessible and should be monitored
for data. It happens in direct response to
ggzcore_server_connect. Note that most events after this will
only happen by calling ggzcore_server_read_data on the server’s
FD!
Parameters:
data NULL
See also:
ggzcore_server_connect
GGZ_CONNECT_FAIL
Error: we have failed to connect to the server. This is
generated in place of GGZ_CONNECTED if the connection could not
be made. The server object is otherwise unaffected.
Parameters:
data An error string (created by strerror)
See also:
ggzcore_server_connect
GGZ_NEGOTIATED
We have negotiated a connection to the server. This will happen
automatically once a connection has been established, if the
server socket is monitored.
Note:
This just means we’ve determined ggzd is at the other end.
Parameters:
data NULL
See also:
ggzcore_server_read_data
GGZ_NEGOTIATE_FAIL
Error: negotiation failure. Could be the wrong version. This
will happen in place of a GGZ_NEGOTIATED if the server could not
be negotiated with.
Parameters:
data A useless error string.
See also:
ggzcore_server_read_data
GGZ_LOGGED_IN
We have successfully logged in. We can now start doing stuff.
This will not happen until the client sends their login
information.
See also:
ggzcore_server_login
Parameters:
data NULL
See also:
ggzcore_server_read_data
GGZ_LOGIN_FAIL
Error: login failure. This will happen in place of GGZ_LOGGED_IN
if the login failed. The server object will be otherwise
unaffected.
Parameters:
data A pointer to a GGZErrorEventData.
See also:
GGZErrorEventData
ggzcore_server_read_data
GGZ_MOTD_LOADED
The MOTD has been read from the server and can be displayed. The
server will send us the MOTD automatically after login; it can
also be requested by ggzcore_server_motd. It is up to the client
whether or not to display it. See the online documentation
(somewhere?) about the MOTD markup format.
Parameters:
data Pointer to a GGZMotdEventData including the full MOTD text.
See also:
ggzcore_server_motd
Todo
The MOTD cannot be accessed outside of this event
See also:
ggzcore_server_read_data!
GGZ_ROOM_LIST
The room list arrived. This will only happen after the list is
requested by ggzcore_server_list_rooms(). The list may be
accessed through ggzcore_server_get_num_rooms() and
ggzcore_server_get_nth_room(). Until this event arrives these
functions will be useless!
Parameters:
data NULL
See also:
ggzcore_server_read_data
GGZ_TYPE_LIST
The list of game types is available. This will only happen after
the list is requested by ggzcore_server_list_types(). The list
may be accessed through ggzcore_server_get_num_gametypes() and
