--- name: "radcli_ctx_apply" section: "3" platform: "linux" package: "radcli" version: "2.0.1-1" release: "Arch Linux 2026-11-01" platforms: ["linux"] url: "https://new.carta.tech/radcli_ctx_apply" --- # radcli\_ctx\_apply(3) Validate the options set so far and initialise the transport. ## NAME radcli\_ctx\_apply - Validate the options set so far and initialise the transport. ## SYNOPSIS ``` #include int radcli_ctx_apply( radcli_ctx *ctx ); ``` ## DESCRIPTION Call once, after all radcli\_ctx\_set\_opt\_str()/\_set\_opt\_int() calls for ctx have been made, to activate the configuration ctx is not usable for a request before this succeeds. radcli\_ctx\_read\_config() calls this internally; do not call it again on a context obtained that way. ## PARAMETERS - **ctx** a context configured via radcli\_ctx\_set\_opt\_str()/\_set\_opt\_int(). ## RETURN VALUE 0 on success, -1 on failure (e.g. no authserver configured, or an invalid radius\_timeout/radius\_retries). ## SEE ALSO [*radcli\_ctx\_free*(3)](/radcli_ctx_free/3.md), [*radcli\_ctx\_get\_opt\_int*(3)](/radcli_ctx_get_opt_int/3.md), [*radcli\_ctx\_get\_opt\_str*(3)](/radcli_ctx_get_opt_str/3.md), [*radcli\_ctx\_new*(3)](/radcli_ctx_new/3.md), [*radcli\_ctx\_read\_config*(3)](/radcli_ctx_read_config/3.md), [*radcli\_ctx\_read\_dictionary*(3)](/radcli_ctx_read_dictionary/3.md), [*radcli\_ctx\_read\_dictionary\_from\_buffer*(3)](/radcli_ctx_read_dictionary_from_buffer/3.md), [*radcli\_ctx\_set\_opt\_int*(3)](/radcli_ctx_set_opt_int/3.md), [*radcli\_ctx\_set\_opt\_str*(3)](/radcli_ctx_set_opt_str/3.md), [*radcli\_ctx\_set\_secret*(3)](/radcli_ctx_set_secret/3.md), [*radcli\_ctx\_set\_tls\_psk*(3)](/radcli_ctx_set_tls_psk/3.md)
