gnutls_heartbeat_ping(3) API function

SYNOPSIS

#include <gnutls/gnutls.h>

int gnutls_heartbeat_ping(gnutls_session_t session, size_t data_size, unsigned int max_tries, unsigned int flags);

ARGUMENTS

gnutls_session_t session
is a gnutls_session_t type.
size_t data_size
is the length of the ping payload.
unsigned int max_tries
if flags is GNUTLS_HEARTBEAT_WAIT then this sets the number of retransmissions. Use zero for indefinite (until timeout).
unsigned int flags
if GNUTLS_HEARTBEAT_WAIT then wait for pong or timeout instead of returning immediately.

DESCRIPTION

This function sends a ping to the peer. If the flags is set to GNUTLS_HEARTBEAT_WAIT then it waits for a reply from the peer.

Note that it is highly recommended to use this function with the flag GNUTLS_HEARTBEAT_WAIT, or you need to handle retransmissions and timeouts manually.

GNUTLS_E_SUCCESS on success, otherwise a negative error code.
