is a gnutls_session_t structure.
contains the data to send.
is the length of the data.
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.
