gnutls_record_recv(3)		    gnutls		 gnutls_record_recv(3)

       gnutls_record_recv - reads data from the TLS record protocol

       #include <gnutls/gnutls.h>

       ssize_t	 gnutls_record_recv(gnutls_session_t  session,	void  *	 data,
       size_t sizeofdata);

       gnutls_session_t session
		   is a gnutls_session_t structure.

       void * data the buffer that the data will be read into

       size_t sizeofdata
		   the number of requested bytes

       This function has the similar semantics with recv().  The only  differ‐
       ence  is	 that  it  accepts  a GnuTLS session, and uses different error

       In the special case that a server requests a renegotiation, the	client
       may receive an error code of GNUTLS_E_REHANDSHAKE.  This message may be
       simply ignored, replied with  an	 alert	GNUTLS_A_NO_RENEGOTIATION,  or
       replied with a new handshake, depending on the client's will.

       If  EINTR  is  returned	by  the internal push function (the default is
       recv()) then GNUTLS_E_INTERRUPTED will be returned.  If GNUTLS_E_INTER‐
       RUPTED or GNUTLS_E_AGAIN is returned, you must call this function again
       to get the data.	 See also gnutls_record_get_direction().

       A server may also receive GNUTLS_E_REHANDSHAKE when a client has initi‐
       ated a handshake. In that case the server can only initiate a handshake
       or terminate the connection.

       the number of bytes received and zero on EOF.  A negative error code is
       returned	 in  case  of an error.	 The number of bytes received might be
       less than sizeofdata.
