.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
These functions decode and encode an \s-1SSL_SESSION\s0 object.
For encoding details see \fBd2i_X509\fR\|(3).
.PP
\&\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).
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBd2i_SSL_SESSION()\fR and \fBd2i_SSL_SESSION_ex()\fR return 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.
.PP
\&\fBi2d_SSL_SESSION()\fR returns the size of the \s-1ASN1\s0 representation in bytes.
When the session is not valid, \fB0\fR is returned and no operation is performed.
