.. 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'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
d2i_SSL_SESSION, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp, long length); int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp); .Ve
"DESCRIPTION"
Header "DESCRIPTION" These functions decode and encode an \s-1SSL_SESSION\s0 object. For encoding details see d2i_X509\|(3).

\s-1SSL_SESSION\s0 objects keep internal link information about the session cache list, when being inserted into one \s-1SSL_CTX\s0 object's session cache. One \s-1SSL_SESSION\s0 object, regardless of its reference count, must therefore only be used with one \s-1SSL_CTX\s0 object (and the \s-1SSL\s0 objects created from this \s-1SSL_CTX\s0 object).

"RETURN VALUES"
Header "RETURN VALUES" \fBd2i_SSL_SESSION() returns a pointer to the newly allocated \s-1SSL_SESSION\s0 object. In case of failure the NULL-pointer is returned and the error message can be retrieved from the error stack.

\fBi2d_SSL_SESSION() returns the size of the \s-1ASN1\s0 representation in bytes. When the session is not valid, 0 is returned and no operation is performed.
