NAME

6       gnutls_record_send2 - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       ssize_t  gnutls_record_send2(gnutls_session_t  session,  const  void  *
12       data, size_t data_size, size_t pad, unsigned flags);
13

ARGUMENTS

15       gnutls_session_t session
16                   is a gnutls_session_t type.
17
18       const void * data
19                   contains the data to send
20
21       size_t data_size
22                   is the length of the data
23
24       size_t pad  padding to be added to the record
25
26       unsigned flags
27                   must be zero
28

DESCRIPTION

30       This function is identical to gnutls_record_send() except that it takes
31       an extra argument to specify padding to be added the record.  To deter‐
32       mine the maximum size of padding, use gnutls_record_get_max_size()  and
33       gnutls_record_overhead_size().
34
35       Note  that  in  order for GnuTLS to provide constant time processing of
36       padding and data in TLS1.3, the flag GNUTLS_SAFE_PADDING_CHECK must  be
37       used in gnutls_init().
38

RETURNS

40       The  number  of  bytes  sent,  or a negative error code.  The number of
41       bytes sent might be less than  data_size .  The maximum number of bytes
42       this function can send in a single call depends on the negotiated maxi‐
43       mum record size.
