In order to successfully accomplish the handshake, the SSL routines need
to know whether they should act in server or client mode. If the generic
method was used, this is not clear from the method itself and must be set
with either SSL_set_connect_state() or SSL_set_accept_state(). If these
routines are not called, the default value set when L<SSL_new(3)|SSL_new(3)>
is called is server mode.
When beginning a new handshake, the SSL engine must know whether it must
call the connect (client) or accept (server) routines. Even though it may
be clear from the method chosen, whether client or server mode was
requested, the handshake routines must be explicitly set.
When using the L<SSL_connect(3)|SSL_connect(3)> or
L<SSL_accept(3)|SSL_accept(3)> routines, the correct handshake
routines are automatically set. When performing a transparent negotiation
using L<SSL_write(3)|SSL_write(3)> or L<SSL_read(3)|SSL_read(3)>, the
handshake routines must be explicitely set in advance using either
SSL_set_connect_state() or SSL_set_accept_state().
