(The method might have been changed with \&\fISSL_CTX_set_ssl_version\fR\|(3) or \&\fISSL_set_ssl_method\fR\|(3).) .PP When beginning a new handshake, the \s-1SSL\s0 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. .PP When using the \fISSL_connect\fR\|(3) or \&\fISSL_accept\fR\|(3) routines, the correct handshake routines are automatically set. When performing a transparent negotiation using \fISSL_write_ex\fR\|(3), \fISSL_write\fR\|(3), \fISSL_read_ex\fR\|(3), or \fISSL_read\fR\|(3), the handshake routines must be explicitly set in advance using either \&\fISSL_set_connect_state()\fR or \fISSL_set_accept_state()\fR. .PP If \fISSL_is_server()\fR is called before \fISSL_set_connect_state()\fR or \&\fISSL_set_accept_state()\fR is called (either automatically or explicitly), the result depends on what method was used when \s-1SSL_CTX\s0 was created with \&\fISSL_CTX_new\fR\|(3). If a generic method or a dedicated server method was passed to \fISSL_CTX_new\fR\|(3), \fISSL_is_server()\fR returns 1; otherwise, it returns 0. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fISSL_set_connect_state()\fR and \fISSL_set_accept_state()\fR do not return diagnostic information. .PP \&\fISSL_is_server()\fR returns 1 if \fBssl\fR is working in server mode or 0 for client mode. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fIssl\fR\|(7), \fISSL_new\fR\|(3), \fISSL_CTX_new\fR\|(3), \&\fISSL_connect\fR\|(3), \fISSL_accept\fR\|(3), \&\fISSL_write_ex\fR\|(3), \fISSL_write\fR\|(3), \fISSL_read_ex\fR\|(3), \fISSL_read\fR\|(3), \&\fISSL_do_handshake\fR\|(3), \&\fISSL_CTX_set_ssl_version\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2017 The OpenSSL Project Authors.
