gnutls_record_recv — API function
#include <gnutls/gnutls.h>
ssize_t
gnutls_record_recv( |
gnutls_session_t session, |
| void * data, | |
size_t data_size); |
is a gnutls_session_t structure.
the buffer that the data will be read into
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 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_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 handshake or terminate the connection.
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
