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
284 * different forms. On platforms that support it the
285 * ASN1_ITEM structure itself will be globally exported.
286 * Other platforms will export a function that returns
287 * an ASN1_ITEM pointer.
288 *
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.
292 *
293 * The structure will look like this:
294 *
295 * typedef struct SOMETHING_st {
296 * ...
297 * ASN1_ITEM_EXP *iptr;
298 * ...
299 * } SOMETHING;

301 * It would be initialised as e.g.:
302 *
303 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
304 *
305 * and the actual pointer extracted with:
306 *
307 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
308 *
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.
