@deftypefun {int} {gnutls_range_split} (gnutls_session_t @var{session}, const gnutls_range_st * @var{orig}, gnutls_range_st * @var{next}, gnutls_range_st * @var{remainder})
@var{session}: is a @code{gnutls_session_t} type
@var{orig}: is the original range provided by the user
@var{next}: is the returned range that can be conveyed in a TLS record
@var{remainder}: is the returned remaining range
This function should be used when it is required to hide the length
of very long data that cannot be directly provided to @code{gnutls_record_send_range()} .
In that case this function should be called with the desired length
hiding range in @code{orig} . The returned @code{next} value should then be used in
the next call to @code{gnutls_record_send_range()} with the partial data.
That process should be repeated until @code{remainder} is (0,0).
@strong{Returns:} 0 in case splitting succeeds, non zero in case of error.
Note that @code{orig} is not changed, while the values of @code{next} and @code{remainder} are modified to store the resulting values.
@end deftypefun
