/* 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.
