ssize_t gnutls_record_recv(gnutls_session_t session, void * data, size_t data_size);
is a gnutls_session_t type.

the number of requested bytes
This function has the similar semantics with recv(). The only
difference is that it accepts a GnuTLS session, and uses different
In the special case that the peer requests a renegotiation, the
caller will receive an error code of GNUTLS_E_REHANDSHAKE. In case
of a client, this message may be simply ignored, replied with an alert
GNUTLS_A_NO_RENEGOTIATION, or replied with a new handshake,
depending on the clients will. A server receiving this error code
can only initiate a new handshake or terminate the session.
If EINTR is returned by the internal push function (the default
is recv()) then GNUTLS_E_INTERRUPTED will be returned. If
GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must
call this function again to get the data. See also
The number of bytes received and zero on EOF (for stream
connections). A negative error code is returned in case of an error.
The number of bytes received might be less than the requested data_size .
