Before issuing any Radius requests, the library must be made aware of the
servers it can contact. The easiest way to configure the library is to
call radius_config(). radius_config()
causes the library to read a configuration file whose format is described
in » radius.conf.
Parameters
radius_handle
file
The pathname of the configuration file is passed as the file argument
to radius_config(). The library can also be
configured programmatically by calls to
radius_add_server().
