gnutls_record_send_range(3) gnutls gnutls_record_send_range(3)
NAME
gnutls_record_send_range - API function
SYNOPSIS
#include <gnutls/gnutls.h>
ssize_t gnutls_record_send_range(gnutls_session_t session, const
void * data, size_t data_size, const gnutls_range_st * range);
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.
const gnutls_range_st * range
is the range of lengths in which the real data length
must be hidden.
DESCRIPTION
This function operates like gnutls_record_send() but, while
gnutls_record_send() adds minimal padding to each TLS record,
this function uses the TLS extra-padding feature to conceal the
real data size within the range of lengths provided. Some TLS
sessions do not support extra padding (e.g. stream ciphers in
standard TLS or SSL3 sessions). To know whether the current
session supports extra padding, and hence length hiding, use the
gnutls_record_can_use_length_hiding() function.
NOTE
This function currently is limited to blocking sockets.
RETURNS
The number of bytes sent (that is data_size in a successful
invocation), or a negative error code.
