gnutls_record_send_early_data - API function
#include <gnutls/gnutls.h>
ssize_t gnutls_record_send_early_data(gnutls_session_t session, const
void * data, size_t data_size);
gnutls_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
This 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.
The 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.
