gnutls_ia_recv(3)						      gnutls							 gnutls_ia_recv(3)

NAME

       gnutls_ia_recv - read data from the TLS/IA protocol

SYNOPSIS

       #include <gnutls/extra.h>

       ssize_t gnutls_ia_recv(gnutls_session_t session, char * data, size_t sizeofdata);

ARGUMENTS

       gnutls_session_t session
		   is a gnutls_session_t structure.

       char * data the buffer that the data will be read into, must hold >= 12 bytes.

       size_t sizeofdata
		   the number of requested bytes, must be >= 12.

DESCRIPTION

       Receive	TLS/IA	data.	This function has the similar semantics with recv().  The only difference is that it accepts a GnuTLS session, and
       uses different error codes.

       If the server attempt to finish an application  phase,  this  function  will  return  GNUTLS_E_WARNING_IA_IPHF_RECEIVED	or  GNUTLS_E_WARN-
       ING_IA_FPHF_RECEIVED.   The  caller  should  then invoke gnutls_ia_verify_endphase(), and if it runs the client side, also send an endphase
       message of its own using gnutls_ia_endphase_send.

       If EINTR is returned by the internal push  function  (the  default  is  code{recv()})  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.

RETURNS

       The number of bytes received.  A negative error	code  is  returned  in	case  of  an  error.   The  GNUTLS_E_WARNING_IA_IPHF_RECEIVED  and
       GNUTLS_E_WARNING_IA_FPHF_RECEIVED errors are returned when an application phase finished message has been sent by the server.

NAME

       gnutls_rehandshake - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_rehandshake(gnutls_session_t session);

ARGUMENTS

       gnutls_session_t session
		   is a gnutls_session_t structure.

DESCRIPTION

       This function will renegotiate security parameters with the client.  This should only be called in case of a server.

       This message informs the peer that we want to renegotiate parameters (perform a handshake).

       If this function succeeds (returns 0), you must call the gnutls_handshake() function in order to negotiate the new parameters.

       Since  TLS is full duplex some application data might have been sent during peer's processing of this message. In that case one should call
       gnutls_record_recv() until GNUTLS_E_REHANDSHAKE is returned to clear any pending data. Care must be taken if rehandshake  is  mandatory	to
       terminate if it does not start after some threshold.

       If  the	client	does  not wish to renegotiate parameters he will should with an alert message, thus the return code will be GNUTLS_E_WARN-
       ING_ALERT_RECEIVED and the alert will be GNUTLS_A_NO_RENEGOTIATION.  A client may also choose to ignore this message.

RETURNS

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.
