gnutls_record_send_range - API function
#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);
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.
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.
This function currently is only limited to blocking sockets.
The number of bytes sent (that is data_size in a successful
invocation), or a negative error code.
