gnutls_record_send_early_data(3) gnutls gnutls_record_send_early_data(3)
NAME
gnutls_record_send_early_data - API function
SYNOPSIS
#include <gnutls/gnutls.h>
gnutls_record_send_early_data(3) session, const
void * data, size_t data_size);
ARGUMENTS
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
DESCRIPTION
This function can be used by a client to send data early in the hand-
shake 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.
RETURNS
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 maxi-
mum record size.
SINCE
3.6.5
