326 | * The following macros and typedefs allow an ASN1_ITEM | |
bb5ea36b DSH |

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 | |
331 | * ASN1_ITEM structure itself will be globally exported. | |
332 | * Other platforms will export a function that returns | |
333 | * an ASN1_ITEM pointer. | |
334 | * | |
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. | |
338 | * | |
339 | * The structure will look like this: | |

343 | * ASN1_ITEM_EXP *iptr; | |

348 | * | |
349 | * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...}; | |
350 | * | |
351 | * and the actual pointer extracted with: | |
352 | * | |
353 | * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr); | |
354 | * | |
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. | |
