NAME
       gnutls_heartbeat_ping - 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 structure.

       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.

RETURNS
       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE
       3.1.2
