SSL_SET_CONNECT_STATE(3)                    DragonFly Library Functions Manual


NAME

     SSL_set_connect_state, SSL_set_accept_state, SSL_is_server - prepare SSL
     object to work in client or server mode


SYNOPSIS

     #include <openssl/ssl.h>

     void
     SSL_set_connect_state(SSL *ssl);

     void
     SSL_set_accept_state(SSL *ssl);

     int
     SSL_is_server(const SSL *ssl);


DESCRIPTION

     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
     SSL_set_ssl_method(3).)

     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
     SSL_set_accept_state().

     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.


RETURN VALUES

     SSL_is_server() returns 1 if ssl is set to server mode or 0 if it is set
     to client mode.
