.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "SSL_set_connect_state 3"
way too many mistakes in technical documents.

\fBSSL_set_accept_state() sets ssl to work in server mode.
\fBSSL_is_server() checks if ssl is working in server mode.
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.
When using the SSL_connect\|(3) or \fBSSL_accept\|(3) routines, the correct handshake routines are automatically set. When performing a transparent negotiation using SSL_write_ex\|(3), SSL_write\|(3), SSL_read_ex\|(3), or SSL_read\|(3), the handshake routines must be explicitly set in advance using either \fBSSL_set_connect_state() or SSL_set_accept_state().
If SSL_is_server() is called before SSL_set_connect_state() or \fBSSL_set_accept_state() is called (either automatically or explicitly), the result depends on what method was used when \s-1SSL_CTX\s0 was created with \fBSSL_CTX_new\|(3). 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.
\fBSSL_is_server() returns 1 if ssl is working in server mode or 0 for client mode.
