gnutls_record_recv_early_data - API function
ssize_t gnutls_record_recv_early_data(gnutls_session_t session, void * data, size_t data_size);
This function can be used by a server to retrieve data sent early in the handshake processes when resuming a session. This is used to implement a zero-roundtrip (0-RTT) mode. It has the same semantics as gnutls_record_recv().
This function can be called either in a handshake hook, or after the handshake is complete.
The number of bytes received and zero when early data reading is
complete. A negative error code is returned in case of an error. If no early
data is received during the handshake, this function returns
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE. The number of bytes received
might be less than the requested
