NAME

       gnutls_record_send2 - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       ssize_t  gnutls_record_send2(gnutls_session_t  session,  const void * data, size_t data_size, size_t pad,
       unsigned flags);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       const void * data
                   contains the data to send

       size_t data_size
                   is the length of the data

       size_t pad  padding to be added to the record

       unsigned flags
                   must be zero

DESCRIPTION

       This function is identical to gnutls_record_send() except that it takes  an  extra  argument  to  specify
       padding    to   be   added   the   record.    To   determine   the   maximum   size   of   padding,   use
       gnutls_record_get_max_size() and gnutls_record_overhead_size().

       Note that in order for GnuTLS to provide constant time processing of padding and data in TLS1.3, the flag
       GNUTLS_SAFE_PADDING_CHECK must be used in gnutls_init().

RETURNS

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

SINCE

       3.6.3
