330 * The following macros and typedefs allow an ASN1_ITEM
331 * to be embedded in a structure and referenced. Since
332 * the ASN1_ITEM pointers need to be globally accessible
333 * (possibly from shared libraries) they may exist in
334 * different forms. On platforms that support it the
335 * ASN1_ITEM structure itself will be globally exported.
336 * Other platforms will export a function that returns
337 * an ASN1_ITEM pointer.
338 *
339 * To handle both cases transparently the macros below
340 * should be used instead of hard coding an ASN1_ITEM
341 * pointer in a structure.
342 *
343 * The structure will look like this:
344 *
345 * typedef struct SOMETHING_st {
346 *      ...
347 *      ASN1_ITEM_EXP *iptr;
348 *      ...
349 * } SOMETHING;
350 *
351 * It would be initialised as e.g.:
352 *
353 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
354 *
355 * and the actual pointer extracted with:
356 *
357 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
358 *
359 * Finally an ASN1_ITEM pointer can be extracted from an
360 * appropriate reference with: ASN1_ITEM_rptr(X509). This
361 * would be used when a function takes an ASN1_ITEM * argument.
