NAME

       gnutls_record_recv - API function


SYNOPSIS

       #include <gnutls/gnutls.h>

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


ARGUMENTS

       gnutls_session_t session
		   is a gnutls_session_t type.

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

       size_t data_size
		   the number of requested bytes


DESCRIPTION

       This function has the similar semantics with recv().  The only  differ-
       ence  is  that  it  accepts  a GnuTLS session, and uses different error
       codes.  In the special case that the peer requests a renegotiation, the
       caller  will receive an error code of GNUTLS_E_REHANDSHAKE.  In case of
       a client, 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. A server receiving this error code can only  ini-
       tiate a new handshake or terminate the session.

       If  EINTR  is  returned	by  the internal pull 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().


RETURNS

       The number of bytes received and zero on EOF (for stream  connections).
       A  negative  error code is returned in case of an error.  The number of
       bytes received might be less than the requested	data_size .
