const char * radcli_ctx_get_opt_str(
    const radcli_ctx  *ctx,
    radcli_opt_id      opt
);
```

## DESCRIPTION

Unlike radcli\_ctx\_set\_opt\_str(), only valid for an RADCLI\_OPT\_TYPE\_STR opt  #RADCLI\_OPT\_AUTHSERVER/#RADCLI\_OPT\_ACCTSERVER (RADCLI\_OPT\_TYPE\_SRV) store a parsed server list, not a string, so are not readable through this call.

## PARAMETERS

- **ctx**

  a context from radcli\_ctx\_new() or radcli\_ctx\_read\_config().

- **opt**

## RETURN VALUE
