gnutls_record_recv_early_data − API function
#include <gnutls/gnutls.h>
ssize_t gnutls_record_recv_early_data(gnutls_session_t session, void * data, size_t data_size);
gnutls_session_t session
is a gnutls_session_t type.
void * data |
the buffer that the data will be read into |
size_t data_size
the number of requested bytes
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
data_size .
