NAME         top

       gnutls_heartbeat_ping - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

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

ARGUMENTS         top

       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         top

       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

RETURNS         top

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.
