NAME
gnutls_record_recv - API function
SYNOPSIS
#include <gnutls/gnutls.h>
gnutls_record_recv(3) 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 .
