DESCRIPTION

     These functions get values from the krb5.conf(5) configuration file, or
     another configuration database specified by the c parameter.

     The variable arguments should be a list of strings naming each subsection
     to look for. For example:

           krb5_config_get_bool_default(context, NULL, FALSE,
                "libdefaults", "log_utc", NULL);

     gets the boolean value for the log_utc option, defaulting to FALSE.

     krb5_config_get_bool_default() will convert the option value to a boolean
     value, where `yes', `true', and any non-zero number means TRUE, and any
     other value FALSE.

     krb5_config_get_int_default() will convert the value to an integer.

     krb5_config_get_time_default() will convert the value to a period of time
     (not a time stamp) in seconds, so the string `2 weeks' will be converted
     to 1209600 (2 * 7 * 24 * 60 * 60).

     krb5_config_get_string() returns a const char * to a string in the con-
     figuration database.  The string may not be valid after a reload of the
     configuration database so a caller should make a local copy if it needs
     to keep the string.

     krb5_config_free_strings() free strings as returned by
     krb5_config_get_strings() and krb5_config_vget_strings().  If the argu-
     ment strings is a NULL pointer, no action occurs.

     krb5_config_file_free() free the result of krb5_config_parse_file() and
     krb5_config_parse_file_multi().

BUGS

     For the default functions, other than for the string case, there's no way
     to tell whether there was a value specified or not.
