D2I_SSL_SESSION(3ossl) OpenSSL D2I_SSL_SESSION(3ossl)
NAME
d2i_SSL_SESSION, d2i_SSL_SESSION_ex, i2d_SSL_SESSION - convert
SSL_SESSION object from/to ASN1 representation
SYNOPSIS
#include <openssl/ssl.h>
SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp,
long length);
SSL_SESSION *d2i_SSL_SESSION_ex(SSL_SESSION **a, const unsigned char **pp,
long length, OSSL_LIB_CTX *libctx,
const char *propq);
int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp);
DESCRIPTION
These functions decode and encode an SSL_SESSION object. For encoding
details see d2i_X509(3).
SSL_SESSION objects keep internal link information about the session
cache list, when being inserted into one SSL_CTX object's session
cache. One SSL_SESSION object, regardless of its reference count, must
therefore only be used with one SSL_CTX object (and the SSL objects
created from this SSL_CTX object).
RETURN VALUES
d2i_SSL_SESSION(3) and d2i_SSL_SESSION_ex() return a pointer to the
newly allocated SSL_SESSION object. In case of failure the NULL-
pointer is returned and the error message can be retrieved from the
error stack.
i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes.
When the session is not valid, 0 is returned and no operation is
performed.

HISTORY
The function d2i_SSL_SESSION_ex() was added in OpenSSL 3.2.
