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.
