.SS "void Server::AddCommand (char * cmd, handlerfunc f, char flags, int minparams, char * source)\fC [virtual]\fP"
.PP
Adds a command to the command table. This allows modules to add extra commands into the command table. You must place a function within your module which is is of type handlerfunc:
.PP
typedef void (handlerfunc) (char**, int, userrec*); ... void \fBhandle_kill(char **parameters, int pcnt, userrec *user)\fP
.PP
When the command is typed, the parameters will be placed into the parameters array (similar to argv) and the parameter count will be placed into pcnt (similar to argv). There will never be any less parameters than the 'minparams' value you specified when creating the command. The *user parameter is the class of the user which caused the command to trigger, who will always have the flag you specified in 'flags' when creating the initial command. For example to create an oper only command create the commands with flags='o'. The source parameter is used for resource tracking, and should contain the name of your module (with file extension) e.g. 'm_blarp.so'. If you place the wrong identifier here, you can cause crashes if your module is unloaded.Definition at line 437 of file modules.cpp.

Adds a E-line The E-line is enforced as soon as it is added. The duration must be in seconds, however you can use the \fBServer::CalcDuration\fP method to convert durations into the 1w2d3h3m6s format used by /GLINE etc. The source is an arbitary string used to indicate who or what sent the data, usually this is the nickname of a person, or a server name.

.fi
.SS "bool Server::AddExtendedListMode (char modechar)\fC [virtual]\fP"
.PP
Adds an extended mode letter which is parsed by a module and handled in a list fashion. This call is used to implement modes like +q and +a. The characteristics of these modes are as follows:
.PP
(1) They are ALWAYS on channels, not on users, therefore their type is MT_CHANNEL
.PP
(2) They always take exactly one parameter when being added or removed
.PP
(3) They can be set multiple times, usually on users in channels
.PP
(4) The mode and its parameter are NOT stored in the channels modes structure
.PP
It is down to the module handling the mode to maintain state and determine what 'items' (e.g. users, or a banlist) have the mode set on them, and process the modes at the correct times, e.g. during access checks on channels, etc. When the extended mode is triggered the OnExtendedMode method will be triggered as above. Note that the target you are given will be a channel, if for example your mode is set 'on a user' (in for example +a) you must use Server::Find to locate the user the mode is operating on. Your mode handler may return 1 to handle the mode AND tell the core to display the mode change, e.g. '+aaa one two three' in the case of the mode for 'two', or it may return -1 to 'eat' the mode change, so the above example would become '+aa one three' after processing.Definition at line 605 of file modules.cpp.

.fi
.SS "bool Server::AddExtendedMode (char modechar, int type, bool requires_oper, int params_when_on, int params_when_off)\fC [virtual]\fP"
.PP
Adds an extended mode letter which is parsed by a module. This allows modules to add extra mode letters, e.g. +x for hostcloak. the 'type' parameter is either MT_CHANNEL, MT_CLIENT, or MT_SERVER, to indicate wether the mode is a channel mode, a client mode, or a server mode. requires_oper is used with MT_CLIENT type modes only to indicate the mode can only be set or unset by an oper. If this is used for MT_CHANNEL type modes it is ignored. params_when_on is the number of modes to expect when the mode is turned on (for type MT_CHANNEL only), e.g. with mode +k, this would have a value of 1. the params_when_off value has a similar value to params_when_on, except it indicates the number of parameters to expect when the mode is disabled. Modes which act in a similar way to channel mode +l (e.g. require a parameter to enable, but not to disable) should use this parameter. The function returns false if the mode is unavailable, and will not attempt to allocate another character, as this will confuse users. This also means that as only one module can claim a specific mode character, the core does not need to keep track of which modules own which modes, which speeds up operation of the server. In this version, a mode can have at most one parameter, attempting to use more parameters will have undefined effects.Definition at line 577 of file modules.cpp.

Calls the handler for a command, either implemented by the core or by another module. You can use this function to trigger other commands in the ircd, such as PRIVMSG, JOIN, KICK etc, or even as a method of callback. By defining command names that are untypeable for users on irc (e.g. those which contain a  or 
.br
) you may use them as callback identifiers. The first parameter to this method is the name of the command handler you wish to call, e.g. PRIVMSG. This will be a command handler previously registered by the core or wih \fBAddCommand()\fP. The second parameter is an array of parameters, and the third parameter is a count of parameters in the array. If you do not pass enough parameters to meet the minimum needed by the handler, the functiom will silently ignore it. The final parameter is the user executing the command handler, used for privilage checks, etc.Definition at line 427 of file modules.cpp.

Sends text from a user to one or more channels (mulicast). This method writes a line of text to all users which share a common channel with a given user, with the user's nick/ident/host combination prepended, as used in PRIVMSG etc commands (see RFC 1459). If the IncludeSender flag is set, then the text is also sent back to the user from which it originated, as seen in NICK (see RFC 1459). Otherwise, it is only sent to the other recipients, as seen in QUIT.Definition at line 498 of file modules.cpp.

.SS "void Server::SendFrom (int Socket, \fBuserrec\fP * User, std::string s)\fC [virtual]\fP"
.PP
Sends text from a user to a socket. This method writes a line of text to an established socket, with the given user's nick/ident /host combination prepended, as used in PRIVSG etc commands (see RFC 1459)Definition at line 457 of file modules.cpp.

.SS "void Server::SendMode (char ** parameters, int pcnt, \fBuserrec\fP * user)\fC [virtual]\fP"
.PP
Sends a servermode. you must format the parameters array with the target, modes and parameters for those modes.
.PP
For example:
.PP
char *modes[3];
.PP
modes[0] = ChannelName;
.PP
modes[1] = '+o';
.PP
modes[2] = user->nick;
.PP
Srv->SendMode(modes,3,user);
.PP
The modes will originate from the server where the command was issued, however responses (e.g. numerics) will be sent to the user you provide as the third parameter. You must be sure to get the number of parameters correct in the pcnt parameter otherwise you could leave your server in an unstable state!Definition at line 442 of file modules.cpp.

.SS "void Server::SendTo (\fBuserrec\fP * Source, \fBuserrec\fP * Dest, std::string s)\fC [virtual]\fP"
.PP
Sends text from a user to another user. This method writes a line of text to a user, with a user's nick/ident /host combination prepended, as used in PRIVMSG etc commands (see RFC 1459) If you specify NULL as the source, then the data will originate from the local server, e.g. instead of:
.PP
:user!ident TEXT
.PP
The format will become:
.PP
:localserver TEXT
.PP
Which is useful for numerics and server notices to single users, etc.Definition at line 462 of file modules.cpp.

.SS "void Server::SendToModeMask (std::string modes, int flags, std::string text)\fC [virtual]\fP"
.PP
Sends to all users matching a mode mask You must specify one or more usermodes as the first parameter. These can be RFC specified modes such as +i, or module provided modes, including ones provided by your own module. In the second parameter you must place a flag value which indicates wether the modes you have given will be logically ANDed or OR'ed. You may use one of either WM_AND or WM_OR. for example, if you were to use:
.PP
Serv->SendToModeMask('xi', WM_OR, 'm00');
.PP
Then the text 'm00' will be sent to all users with EITHER mode x or i. Conversely if you used WM_AND, the user must have both modes set to receive the message.Definition at line 385 of file modules.cpp.

.PP
Remove a user's connection to the irc server, but leave their client in existence in the user hash. When you call this function, the user's file descriptor will be replaced with the value of FD_MAGIC_NUMBER and their old file descriptor will be closed. This idle client will remain until it is restored with a valid file descriptor, or is removed from IRC by an operator After this call, the pointer to user will be invalid.Definition at line 619 of file modules.cpp.
