283 * The following macros and typedefs allow an ASN1_ITEM
284 * to be embedded in a structure and referenced. Since
285 * the ASN1_ITEM pointers need to be globally accessible
286 * (possibly from shared libraries) they may exist in
287 * different forms. On platforms that support it the

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

304 * It would be initialised as e.g.:
306 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
308 * and the actual pointer extracted with:
310 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
312 * Finally an ASN1_ITEM pointer can be extracted from an
313 * appropriate reference with: ASN1_ITEM_rptr(X509). This
314 * would be used when a function takes an ASN1_ITEM * argument.
320 * Platforms that can't easily handle shared global variables are declared as
321 * functions returning ASN1_ITEM pointers.
