Detailed Description

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.

Member Function Documentation

void Server::AddCommand (  char *    cmd,
handlerfunc    f,
char    flags,
int    minparams
)  [virtual]
 

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:

typedef void (handlerfunc) (char**, int, userrec*); ... void handle_kill(char **parameters, int pcnt, userrec *user)

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'.

bool Server::AddExtendedMode (  char    modechar,
int    type,
bool    default_on,
int    params_when_on,
int    params_when_off
)  [virtual]
 

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. default_on is true if the mode is to be applied to default connections. 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 +b, 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.

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.
