16
17 SSL_set_connect_state() sets B<ssl> to work in client mode.
18
19 SSL_set_accept_state() sets B<ssl> to work in server mode.

21 =head1 NOTES
22
23 When the SSL_CTX object was created with L<SSL_CTX_new(3)|SSL_CTX_new(3)>,
24 it was either assigned a dedicated client method, a dedicated server
25 method, or a generic method, that can be used for both client and
26 server connections. (The method might have been changed with
27 L<SSL_CTX_set_ssl_version(3)|SSL_CTX_set_ssl_version(3)> or
28 SSL_set_ssl_method().)
29
30 When beginning a new handshake, the SSL engine must know whether it must
31 call the connect (client) or accept (server) routines. Even though it may
32 be clear from the method chosen, whether client or server mode was
33 requested, the handshake routines must be explicitly set.
34
35 When using the L<SSL_connect(3)|SSL_connect(3)> or
36 L<SSL_accept(3)|SSL_accept(3)> routines, the correct handshake
37 routines are automatically set. When performing a transparent negotiation
38 using L<SSL_write(3)|SSL_write(3)> or L<SSL_read(3)|SSL_read(3)>, the
39 handshake routines must be explicitly set in advance using either
40 SSL_set_connect_state() or SSL_set_accept_state().
41
42 =head1 RETURN VALUES
43
44 SSL_set_connect_state() and SSL_set_accept_state() do not return diagnostic
45 information.
