-/* Types
- *
- * This header file provides typedefs for the abstract types used by libpkix.
- * It also provides several useful macros.
- *
- * Note that all these abstract types are typedef'd as opaque structures. This
- * is intended to discourage the caller from looking at the contents directly,
- * since the format of the contents may change from one version of the library
- * to the next. Instead, callers should only access these types using the
- * functions defined in the public header files.
- *
- * An instance of an abstract type defined in this file is called an "object"
- * here, although C does not have real support for objects.
- *
- * Because C does not typically have automatic garbage collection, the caller
- * is expected to release the reference to any object that they create or that
- * is returned to them by a libpkix function. The caller should do this by
- * using the PKIX_PL_Object_DecRef function. Note that the caller should not
- * release the reference to an object if the object has been passed to a
- * libpkix function and that function has not returned.
- *
- * Please refer to libpkix Programmer's Guide for more details.
