@var{version}: is a @code{gnutls_protocol_t}  value

@var{cipher}: is a @code{gnutls_cipher_algorithm_t}  value

@var{flags}: must be zero

This function will return the set size in bytes of the overhead
due to TLS (or DTLS) per record.

Note that this function may provide inacurate values when TLS
extensions that modify the record format are negotiated. In these
cases a more accurate value can be obtained using @code{gnutls_record_overhead_size()}  
after a completed handshake.
