gnutls_record_recv

gnutls_record_recv(3)						      gnutls						     gnutls_record_recv(3)

NAME

       gnutls_record_recv - reads data from the TLS record protocol

SYNOPSIS

       #include <gnutls/gnutls.h>

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

ARGUMENTS

       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

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_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 initiated a handshake. In that case the server can only initiate  a  hand-
       shake or terminate the connection.

RETURNS

       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.
