NAMEgnutls_record_send_early_data − API function

---

SYNOPSIS#include <gnutls/gnutls.h> ssize_t gnutls_record_send_early_data(gnutls_session_t session, const void * data, size_t data_size);

---

ARGUMENTSgnutls_session_t session is a gnutls_session_t type. const void * data contains the data to send size_t data_size is the length of the data

---

DESCRIPTIONThis function can be used by a client to send data early in the handshake processes when resuming a session. This is used to implement a zero−roundtrip (0−RTT) mode. It has the same semantics as gnutls_record_send(). There may be a limit to the amount of data sent as early data. Use gnutls_record_get_max_early_data_size() to check the limit. If the limit exceeds, this function returns GNUTLS_E_RECORD_LIMIT_REACHED.

---

RETURNSThe number of bytes sent, or a negative error code. The number of bytes sent might be less than data_size . The maximum number of bytes this function can send in a single call depends on the negotiated maximum record size.
