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

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

@var{mac}: is a @code{gnutls_mac_algorithm_t}  value

@var{comp}: is a @code{gnutls_compression_method_t}  value (ignored)

@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.

@strong{Since:} 3.2.2
