@ -88,12 +88,5 @@ The function is called whenever a (local) client needs to be checked against
a +bqeI entry of the given extban type, and whenever a local client tries to
add such an entry. (Clients are allowed to add bans matching themselves.)
There is a convenience function which allows extbans to be stacked:
extern int match_child(const char *banstr, struct Client *client_p, struct Channel *chptr, long mode_type);
The arguments are as follows:
banstr: the text after the parent banstr (extb functions already get the mask this way)
client_p: the client to check; this is always a local client, which may be
on or off channel
chptr: the channel
mode_type: CHFL_BAN, CHFL_QUIET, CHFL_EXCEPTION or CHFL_INVEX
