Function s2n_tls_sys::s2n_recv_early_data

pub unsafe extern "C" fn s2n_recv_early_data(
    conn: *mut s2n_connection,
    data: *mut u8,
    max_data_len: isize,
    data_received: *mut isize,
    blocked: *mut Type
) -> c_int

Called by the server to begin negotiation and accept any early data the client sends.

See https://github.com/aws/s2n-tls/blob/main/docs/usage-guide/topics/ch14-early-data.md for usage and examples. DO NOT USE unless you have considered the security issues and implemented mitigation for anti-replay attacks.

@param conn A pointer to the connection @param data A pointer to a buffer to store the early data received @param max_data_len The size of the early data buffer @param data_received A pointer which will be set to the size of the early data received @param blocked A pointer which will be set to the blocked status, as in s2n_negotiate. @returns A POSIX error signal. The error should be handled as in s2n_negotiate.
