326 * The following macros and typedefs allow an ASN1_ITEM
327 * to be embedded in a structure and referenced. Since
328 * the ASN1_ITEM pointers need to be globally accessible
329 * (possibly from shared libraries) they may exist in
330 * different forms. On platforms that support it the

332 * Other platforms will export a function that returns
333 * an ASN1_ITEM pointer.
335 * To handle both cases transparently the macros below
336 * should be used instead of hard coding an ASN1_ITEM
337 * pointer in a structure.
339 * The structure will look like this:
341 * typedef struct SOMETHING_st {
343 * ASN1_ITEM_EXP *iptr;
347 * It would be initialised as e.g.:
349 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
351 * and the actual pointer extracted with:
353 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
355 * Finally an ASN1_ITEM pointer can be extracted from an
356 * appropriate reference with: ASN1_ITEM_rptr(X509). This
357 * would be used when a function takes an ASN1_ITEM * argument.
363 * Platforms that can't easily handle shared global variables are declared as
364 * functions returning ASN1_ITEM pointers.
