288 * The following macros and typedefs allow an ASN1_ITEM
289 * to be embedded in a structure and referenced. Since
290 * the ASN1_ITEM pointers need to be globally accessible
291 * (possibly from shared libraries) they may exist in
292 * different forms. On platforms that support it the
293 * ASN1_ITEM structure itself will be globally exported.
294 * Other platforms will export a function that returns
295 * an ASN1_ITEM pointer.
297 * To handle both cases transparently the macros below
298 * should be used instead of hard coding an ASN1_ITEM
299 * pointer in a structure.
301 * The structure will look like this:
303 * typedef struct SOMETHING_st {
305 * ASN1_ITEM_EXP *iptr;
309 * It would be initialised as e.g.:
311 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
313 * and the actual pointer extracted with:
315 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
317 * Finally an ASN1_ITEM pointer can be extracted from an
318 * appropriate reference with: ASN1_ITEM_rptr(X509). This
319 * would be used when a function takes an ASN1_ITEM * argument.
325 * Platforms that can't easily handle shared global variables are declared as
326 * functions returning ASN1_ITEM pointers.
