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.
