gnutls_record_send_early_data(3) gnutls gnutls_record_send_early_data(3)

NAME         top

       gnutls_record_send_early_data - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_send_early_data(gnutls_session_t session,
       const void * data, size_t data_size);

ARGUMENTS         top

       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         top

       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.

RETURNS         top

       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.
