| 39SSL_SESSION objects keep internal link information about the session cache 40list, when being inserted into one SSL_CTX object's session cache. 41One SSL_SESSION object, regardless of its reference count, must therefore 42only be used with one SSL_CTX object (and the SSL objects created 43from this SSL_CTX object). 44 |

| 35When using i2d_SSL_SESSION(), the memory location pointed to by B<pp> must be 36large enough to hold the binary representation of the session. There is no 37known limit on the size of the created ASN1 representation, so the necessary 38amount of space should be obtained by first calling i2d_SSL_SESSION() with 39B<pp=NULL>, and obtain the size needed, then allocate the memory and 40call i2d_SSL_SESSION() again. 41 42=head1 RETURN VALUES 43 44d2i_SSL_SESSION() returns a pointer to the newly allocated SSL_SESSION 45object.
