Allows server output and query functions This class contains methods which allow a module to query the state of the irc server, and produce output to users and other servers. 

All modules should instantiate at least one copy of this class, and use its member functions to perform their tasks.

.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 435 of file modules.cpp.

.PP
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 580 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 560 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 425 of file modules.cpp.
