NAME
gnutls_record_recv_early_data - API function
SYNOPSIS
#include <gnutls/gnutls.h>
gnutls_record_recv_early_data(3) session, void *
data, size_t data_size);
ARGUMENTS
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
DESCRIPTION
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.
RETURNS
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 .
SINCE
3.6.5
