SSL_SET_CONNECT_STATE(3) DragonFly Library Functions Manual
SSL_set_connect_state, SSL_set_accept_state, SSL_is_server - prepare SSL
object to work in client or server mode
SSL_is_server(const SSL *ssl);
SSL_set_connect_state() sets ssl to work in client mode.
SSL_set_accept_state() sets ssl to work in server mode.
SSL_is_server() checks whether ssl is set to server mode.
When the SSL_CTX object was created with SSL_CTX_new(3), it was either
assigned a dedicated client method, a dedicated server method, or a
generic method, that can be used for both client and server connections.
(The method might have been changed with SSL_CTX_set_ssl_version(3) or
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 SSL_connect(3) or SSL_accept(3) routines, the correct
handshake routines are automatically set. When performing a transparent
negotiation using SSL_write(3) or SSL_read(3), the handshake routines
must be explicitly set in advance using either SSL_set_connect_state() or
If SSL_is_server() is called before SSL_set_connect_state() or
SSL_set_accept_state() was called either automatically or explicitly, the
result depends on what method was used when the SSL_CTX was created. If
a generic method or a dedicated server method was passed to
SSL_CTX_new(3), SSL_is_server() returns 1; otherwise, it returns 0.
SSL_is_server() returns 1 if ssl is set to server mode or 0 if it is set
to client mode.
