.. 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_SESSION_GET0_CIPHER 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
SSL_SESSION_get0_cipher, SSL_SESSION_set_cipher \- set and retrieve the SSL cipher associated with a session Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& const SSL_CIPHER *SSL_SESSION_get0_cipher(const SSL_SESSION *s); int SSL_SESSION_set_cipher(SSL_SESSION *s, const SSL_CIPHER *cipher); .Ve Header "DESCRIPTION" \fBSSL_SESSION_get0_cipher() retrieves the cipher that was used by the connection when the session was created, or \s-1NULL\s0 if it cannot be determined.

The value returned is a pointer to an object maintained within s and should not be released.

\fBSSL_SESSION_set_cipher() can be used to set the ciphersuite associated with the \s-1SSL_SESSION\s0 s to cipher. For example, this could be used to set up a session based \s-1PSK\s0 (see SSL_CTX_set_psk_use_session_callback\|(3)).

Header "RETURN VALUES" \fBSSL_SESSION_get0_cipher() returns the \s-1SSL_CIPHER\s0 associated with the \s-1SSL_SESSION\s0 or \s-1NULL\s0 if it cannot be determined.

\fBSSL_SESSION_set_cipher() returns 1 on success or 0 on failure.
