NAME

gnutls_record_recv_early_data - API function

SYNOPSIS

#include <gnutls/gnutls.h> ssize_t gnutls_record_recv_early_data(gnutls_session_t 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
