gnutls_record_recv - reads data from the TLS record protocol
ssize_t gnutls_record_recv(gnutls_session_t session, void * data,
is a gnutls_session_t structure.
void * data the buffer that the data will be read into
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 a server requests a renegotiation, the client
may receive an error code of GNUTLS_E_REHANDSHAKE. 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.
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
A server may also receive GNUTLS_E_REHANDSHAKE when a client has
initiated a handshake. In that case the server can only initiate a
handshake or terminate the connection.
the number of bytes received and zero on EOF. A negative error code is
returned in case of an error. The number of bytes received might be
less than sizeofdata.
