 365  * an ASN1_ITEM pointer.
 366  *
 367  * To handle both cases transparently the macros below
 368  * should be used instead of hard coding an ASN1_ITEM
 369  * pointer in a structure.
 370  *
 371  * The structure will look like this:
 372  *
 373  * typedef struct SOMETHING_st {
 374  *      ...
 375  *      ASN1_ITEM_EXP *iptr;
 376  *      ...
 377  * } SOMETHING;
 378  *
 379  * It would be initialised as e.g.:
 380  *
 381  * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
 382  *
 383  * and the actual pointer extracted with:
 384  *
 385  * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
 386  *
 387  * Finally an ASN1_ITEM pointer can be extracted from an
 388  * appropriate reference with: ASN1_ITEM_rptr(X509). This
 389  * would be used when a function takes an ASN1_ITEM * argument.
