 =head1 DESCRIPTION
 
 SSL_set_connect_state() sets B<ssl> to work in client mode.
 
 SSL_set_accept_state() sets B<ssl> to work in server mode.
 
+SSL_is_server() checks if B<ssl> is working in server mode.

 the handshake routines must be explicitly set in advance using either

+If SSL_is_server() is called before SSL_set_connect_state() or
+SSL_set_accept_state() is called (either automatically or explicitly),
+the result depends on what method was used when SSL_CTX was created with
+L<SSL_CTX_new(3)>. If a generic method or a dedicated server method was
+passed to L<SSL_CTX_new(3)>, SSL_is_server() returns 1; otherwise, it returns 0.

 =head1 RETURN VALUES
 
 SSL_set_connect_state() and SSL_set_accept_state() do not return diagnostic
 information.
 
+SSL_is_server() returns 1 if B<ssl> is working in server mode or 0 for client mode.
