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
       difference 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 initiate 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_INTERRUPTED 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 .
