| 18 | =head1 DESCRIPTION
|
|---|
| 19 |
|
|---|
| 20 | These functions decode and encode an SSL_SESSION object.
|
|---|
| 21 | For encoding details see L<d2i_X509(3)>.
|
|---|
| 22 |
|
|---|
| 23 | SSL_SESSION objects keep internal link information about the session cache
|
|---|
| 24 | list, when being inserted into one SSL_CTX object's session cache.
|
|---|
| 25 | One SSL_SESSION object, regardless of its reference count, must therefore
|
|---|
| 26 | only be used with one SSL_CTX object (and the SSL objects created
|
|---|
| 27 | from this SSL_CTX object).
|
|---|
| 28 |
|
|---|
| 29 | =head1 RETURN VALUES
|
|---|
| 30 |
|
|---|
| 31 | d2i_SSL_SESSION() and d2i_SSL_SESSION_ex() return a pointer to the newly
|
|---|
| 32 | allocated SSL_SESSION object.
|
|---|
| 33 | In case of failure the NULL-pointer is returned and the error message
|
|---|
| 34 | can be retrieved from the error stack.
|
|---|
| 35 |
|
|---|
| 36 | i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes.
|
|---|
| 37 | When the session is not valid, B<0> is returned and no operation is performed.
