/* The following macros and typedefs allow an ASN1_ITEM

 * the ASN1_ITEM pointers need to be globally accessible
 * (possibly from shared libraries) they may exist in
 * different forms. On platforms that support it the
 * ASN1_ITEM structure itself will be globally exported.
 * Other platforms will export a function that returns
 * an ASN1_ITEM pointer.
 *
 * To handle both cases transparently the macros below
 * should be used instead of hard coding an ASN1_ITEM
 * pointer in a structure.
 *
 * The structure will look like this:
 *
 * typedef struct SOMETHING_st {
 *      ...
 *      ASN1_ITEM_EXP *iptr;
 *      ...
 * } SOMETHING;
 *
 * It would be initialised as e.g.:
 *
 * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
 *
 * and the actual pointer extracted with:
 *
 * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
 *
 * Finally an ASN1_ITEM pointer can be extracted from an
 * appropriate reference with: ASN1_ITEM_rptr(X509). This
 * would be used when a function takes an ASN1_ITEM * argument.
