0042  * These are the possible values for the itype field of the
0043  * ASN1_ITEM structure and determine how it is interpreted.
0044  *
0045  * For PRIMITIVE types the underlying type
0046  * determines the behaviour if items is NULL.
0047  *
0048  * Otherwise templates must contain a single
0049  * template and the type is treated in the
0050  * same way as the type specified in the template.
0051  *
0052  * For SEQUENCE types the templates field points
0053  * to the members, the size field is the
0054  * structure size.
0055  *
0056  * For CHOICE types the templates field points
0057  * to each possible member (typically a union)
0058  * and the 'size' field is the offset of the
0059  * selector.
0060  *
0061  * The 'funcs' field is used for application-specific
0062  * data and functions.
0063  *
0064  * The EXTERN type uses a new style d2i/i2d.
0065  * The new style should be used where possible
0066  * because it avoids things like the d2i IMPLICIT
0067  * hack.
0068  *
0069  * MSTRING is a multiple string type, it is used
0070  * for a CHOICE of character strings where the
0071  * actual strings all occupy an ASN1_STRING
0072  * structure. In this case the 'utype' field
0073  * has a special meaning, it is used as a mask
0074  * of acceptable types using the B_ASN1 constants.
0075  *
0076  * NDEF_SEQUENCE is the same as SEQUENCE except
0077  * that it will use indefinite length constructed
0078  * encoding if requested.

0670  * This is the ASN1_AUX structure: it handles various miscellaneous
0671  * requirements. For example the use of reference counts and an informational
0672  * callback. The "informational callback" is called at various points during
0673  * the ASN1 encoding and decoding. It can be used to provide minor
0674  * customisation of the structures used. This is most useful where the
0675  * supplied routines *almost* do the right thing but need some extra help at
0676  * a few points. If the callback returns zero then it is assumed a fatal
0677  * error has occurred and the main operation should be abandoned. If major
0678  * changes in the default behaviour are required then an external type is
0679  * more appropriate.
0680  * For the operations ASN1_OP_I2D_PRE, ASN1_OP_I2D_POST, ASN1_OP_PRINT_PRE, and
0681  * ASN1_OP_PRINT_POST, meanwhile a variant of the callback with const parameter
0682  * 'in' is provided to make clear statically that its input is not modified. If
0683  * and only if this variant is in use the flag ASN1_AFLG_CONST_CB must be set.
