## DESCRIPTION

These functions get values from the [krb5.conf(5)](/krb5.conf/5.md) 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 configuration 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 argument *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.
