  3. d2i_SSL_SESSION, d2i_SSL_SESSION_ex, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation
  4. =head1 SYNOPSIS
  5. #include <openssl/ssl.h>
  6. SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp,
  7. long length);
  8. SSL_SESSION *d2i_SSL_SESSION_ex(SSL_SESSION **a, const unsigned char **pp,
  9. long length, OSSL_LIB_CTX *libctx,
  10. const char *propq);
  11. int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp);
  12. =head1 DESCRIPTION
  13. These functions decode and encode an SSL_SESSION object.
  14. For encoding details see L<d2i_X509(3)>.
  15. SSL_SESSION objects keep internal link information about the session cache
  16. list, when being inserted into one SSL_CTX object's session cache.
  17. One SSL_SESSION object, regardless of its reference count, must therefore
  18. only be used with one SSL_CTX object (and the SSL objects created
  19. from this SSL_CTX object).
  20. =head1 RETURN VALUES
  21. d2i_SSL_SESSION() and d2i_SSL_SESSION_ex() return a pointer to the newly
  22. allocated SSL_SESSION object.
  23. In case of failure the NULL-pointer is returned and the error message
  24. can be retrieved from the error stack.
  25. i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes.
  26. When the session is not valid, B<0> is returned and no operation is performed.
