gnutls_heartbeat_ping - API function
#include <gnutls/gnutls.h>
int gnutls_heartbeat_ping(gnutls_session_t session, size_t data_size, unsigned int max_tries, unsigned int flags);
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.
The total TLS data transmitted as part of the ping message are given by the following formula: MAX(16, data_size )+gnutls_record_overhead_size()+3.
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
