Описание (Description)
This function has the similar semantics with recv(). The only
difference is that it accepts a GnuTLS session, and uses
different error codes. 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 client's will. A server receiving this error
code can only initiate a new handshake or terminate the session.
If EINTR is returned by the internal pull 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
gnutls_record_get_direction().
Возвращаемое значение (Return value)
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 .
