gnutls_est_record_overhead_size — API function


#include <gnutls/gnutls.h>

size_t gnutls_est_record_overhead_size(gnutls_protocol_t version, gnutls_cipher_algorithm_t cipher, gnutls_mac_algorithm_t mac, gnutls_compression_method_t comp, unsigned int flags);


gnutls_protocol_t version

is a gnutls_protocol_t value

gnutls_cipher_algorithm_t cipher

is a gnutls_cipher_algorithm_t value

gnutls_mac_algorithm_t mac

is a gnutls_mac_algorithm_t value

gnutls_compression_method_t comp

is a gnutls_compression_method_t value (ignored)

unsigned int 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 gnutls_record_overhead_size()  after a completed handshake.
