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 structure.

       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 difference is that it accepts a GnuTLS session, and uses different error
       codes.  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_INTERRUPTED  or  GNUTLS_E_AGAIN is returned, you must call this function again to get the data.  See also gnutls_record_get_direc-
       tion().	A server may also receive GNUTLS_E_REHANDSHAKE when a client has initiated a handshake. In that case the server can only  initiate
       a handshake or terminate the connection.

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 .
