It may either be instantiated with one parameter or none. Constructing the class using one parameter allows you to specify a path to your own configuration file, otherwise, inspircd.conf is read. .PP Definition at line 1072 of file modules.h. .SH "Constructor & Destructor Documentation" .PP .SS "ConfigReader::ConfigReader ()" .PP Default constructor.

This method counts the number of times a tag appears in a config file, for use where there are several tags of the same kind, e.g. with opers and connect types.
