gnutls_record_send(3)						      gnutls						     gnutls_record_send(3)

NAME

       gnutls_record_send - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_send(gnutls_session_t session, const void * data, size_t data_size);

ARGUMENTS

       gnutls_session_t session
		   is a gnutls_session_t structure.

       const void * data
		   contains the data to send

       size_t data_size
		   is the length of the data

DESCRIPTION

       This  function  has  the  similar semantics with send().  The only difference is that it accepts a GnuTLS session, and uses different error
       codes.  Note that if the send buffer is full, send() will block this function.  See the send() documentation for full information.  You can
       replace	the  default  push  function  by using gnutls_transport_set_ptr2() with a call to send() with a MSG_DONTWAIT flag if blocking is a
       problem.  If the EINTR is returned by the internal push function (the default is send()) then GNUTLS_E_INTERRUPTED  will  be  returned.	If
       GNUTLS_E_INTERRUPTED  or  GNUTLS_E_AGAIN  is returned, you must call this function again, with the same parameters; alternatively you could
       provide a NULL pointer for data, and 0 for size. cf. gnutls_record_get_direction(). The errno value EMSGSIZE maps to GNUTLS_E_LARGE_PACKET.

RETURNS

       The number of bytes sent, or a negative error code.  The number of bytes sent might be less than  data_size .  The maximum number of  bytes
       this function can send in a single call depends on the negotiated maximum record size.

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
