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
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.
