gnutls_record_recv_early_data - API function
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 searver 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
number of bytes received might be less than the requested
