radius_config — Causes the library to read the given configuration file
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.
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().
Returns TRUE on success or FALSE on failure.
