NAME

6       gnutls_record_recv - reads data from the TLS record protocol
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       ssize_t   gnutls_record_recv(gnutls_session_t  session,  void  *  data,
12       size_t sizeofdata);
13

ARGUMENTS

15       gnutls_session_t session
16                   is a gnutls_session_t structure.
17
18       void * data the buffer that the data will be read into
19
20       size_t sizeofdata
21                   the number of requested bytes
22

DESCRIPTION

24       This function has the similar semantics with recv(). The  only  differ‐
25       ence  is  that  is  accepts  a GNUTLS session, and uses different error
26       codes.
27
28       In the special case that a server requests a renegotiation, the  client
29       may receive an error code of GNUTLS_E_REHANDSHAKE.  This message may be
30       simply ignored, replied with an alert containing  NO_RENEGOTIATION,  or
31       replied with a new handshake, depending on the client's will.
32
33       If  EINTR  is  returned  by  the internal push function (the default is
34       code{recv()})  then   GNUTLS_E_INTERRUPTED   will   be   returned.   If
35       GNUTLS_E_INTERRUPTED  or GNUTLS_E_AGAIN is returned, you must call this
36       function again to get the data.  See also code{gnutls_record_get_direc‐
37       tion()}.
38
39       A server may also receive GNUTLS_E_REHANDSHAKE when a client has initi‐
40       ated a handshake. In that case the server can only initiate a handshake
41       or terminate the connection.
42
43       Returns the number of bytes received and zero on EOF.  A negative error
44       code is returned in case of an error.  The  number  of  bytes  received
45       might be less than code{count}.
