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
