280 * The following macros and typedefs allow an ASN1_ITEM
281 * to be embedded in a structure and referenced. Since
282 * the ASN1_ITEM pointers need to be globally accessible
283 * (possibly from shared libraries) they may exist in

287 * an ASN1_ITEM pointer.
289 * To handle both cases transparently the macros below
290 * should be used instead of hard coding an ASN1_ITEM
291 * pointer in a structure.
293 * The structure will look like this:
295 * typedef struct SOMETHING_st {

301 * It would be initialised as e.g.:
303 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
305 * and the actual pointer extracted with:
307 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
309 * Finally an ASN1_ITEM pointer can be extracted from an
310 * appropriate reference with: ASN1_ITEM_rptr(X509). This
311 * would be used when a function takes an ASN1_ITEM * argument.
