.RE
.PP
The data inserted into the reference list is a table as it is an arbitary pointer compared to other users by its memory address, as this is a very fast 32 or 64 bit integer comparison.

.SS "\fBstd::string\fP chanrec::GetModeParameter (char mode)"
.PP
Returns the parameter for a custom mode on a channel. 
.PP
\fBParameters:\fP
.RS 4
\fImode\fP The mode character you wish to query
.RE
.PP
For example if '+L #foo' is set, and you pass this method 'L', it will return 'foo'. If the mode is not set on the channel, or the mode has no parameters associated with it, it will return an empty string.
.PP
\fBReturns:\fP
.RS 4
The parameter for this mode is returned, or an empty string

Obrain the internal reference list The internal reference list contains a list of userrec* cast to char*.

These are used for rapid comparison to determine channel membership for PRIVMSG, NOTICE, QUIT, PART etc. The resulting pointer to the vector should be considered readonly and only modified via AddUser and DelUser.

This function returns a vector of userrec pointers, each of which has been casted to char* to prevent circular references
