Синопсис (Synopsis)

#include <gnutls/gnutls.h>

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

Аргументы (Arguments)

gnutls_session_t session
                   is a gnutls_session_t type.

       void * data the buffer that the data will be read into

       size_t data_size
                   the number of requested bytes

Описание (Description)

This function can be used by a server to retrieve data sent 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_recv().

       This function can be called either in a handshake hook, or after
       the handshake is complete.

Возвращаемое значение (Return value)

The number of bytes received and zero when early data reading is
       complete.  A negative error code is returned in case of an error.
       If no early data is received during the handshake, this function
       returns GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE.  The number of
       bytes received might be less than the requested
        data_size .
