NAME

6       gnutls_record_recv - API function
7

SYNOPSIS

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

ARGUMENTS

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

DESCRIPTION

24       This function has the similar semantics with recv().  The only  differ‐
25       ence  is  that  it  accepts  a GnuTLS session, and uses different error
26       codes.  In the special case that the peer requests a renegotiation, the
27       caller  will receive an error code of GNUTLS_E_REHANDSHAKE.  In case of
28       a client, this message may be simply ignored,  replied  with  an  alert
29       GNUTLS_A_NO_RENEGOTIATION,  or  replied with a new handshake, depending
30       on the client's will. A server receiving this error code can only  ini‐
31       tiate a new handshake or terminate the session.
32
33       If  EINTR  is  returned  by  the internal pull function (the default is
34       recv()) then GNUTLS_E_INTERRUPTED will be returned.  If GNUTLS_E_INTER‐
35       RUPTED or GNUTLS_E_AGAIN is returned, you must call this function again
36       to get the data.  See also gnutls_record_get_direction().
37

RETURNS

39       The number of bytes received and zero on EOF (for stream  connections).
40       A  negative  error code is returned in case of an error.  The number of
41       bytes received might be less than the requested  data_size .
