gnutls_record_recv - API function
#include <gnutls/gnutls.h>
ssize_t gnutls_record_recv(gnutls_session_t session, void * data,
size_t data_size);
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
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().
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 .
