int radcli_ctx_set_opt_str(
    radcli_ctx   *ctx,
    radcli_opt_id opt,
    const char   *val
);

Stores val for opt on ctx, validating it against opt's own grammar (e.g. #RADCLI_OPT_AUTHSERVER accepts the "host[:port[:secret]]" form a config file's authserver line does). Valid for any radcli_opt_id whose RC_OPTION_TABLE type is RADCLI_OPT_TYPE_STR or RADCLI_OPT_TYPE_SRV; use radcli_ctx_set_opt_int() for an RADCLI_OPT_TYPE_INT option instead.

the value; for #RADCLI_OPT_AUTHSERVER/#RADCLI_OPT_ACCTSERVER, the shared secret is better set with radcli_ctx_set_secret() than embedded in this string.

0 on success, -1 on failure (NULL ctx, opt out of range, wrong type for opt, or an invalid val for opt's grammar).
