759 | * This is the ASN1_AUX structure: it handles various miscellaneous | |
760 | * requirements. For example the use of reference counts and an informational | |
761 | * callback. The "informational callback" is called at various points during | |
762 | * the ASN1 encoding and decoding. It can be used to provide minor | |
763 | * customisation of the structures used. This is most useful where the | |
764 | * supplied routines *almost* do the right thing but need some extra help at | |
765 | * a few points. If the callback returns zero then it is assumed a fatal | |
766 | * error has occurred and the main operation should be abandoned. If major | |
767 | * changes in the default behaviour are required then an external type is | |
768 | * more appropriate. | |
