NAME
       gnutls_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);

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 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
       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.

SINCE
       3.6.5
