gnutls_record_send_range(3)      gnutls      gnutls_record_send_range(3)

NAME         top

       gnutls_record_send_range - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       This function currently is limited to blocking sockets.

RETURNS         top

       The number of bytes sent (that is data_size in a successful
       invocation), or a negative error code.
