/* Definitions for Ghostscript modules that define allocatable structures */
/* Requires gstypes.h */

#ifndef gsstruct_INCLUDED
#  define gsstruct_INCLUDED

#include "gsstype.h"

/*
 * Ghostscript structures are defined with names of the form (gs_)xxx_s,
 * with a corresponding typedef of the form (gs_)xxx or (gs_)xxx_t.
 * By extension, the structure descriptor is named st_[gs_]xxx.
 * (Note that the descriptor name may omit the gs_ even if the type has it.)
 * Structure descriptors are always allocated statically and are
 * always const; they may be either public or private.
 *
 * In order to ensure that there is a descriptor for each structure type,
 * we require, by convention, that the following always appear together
 * if the structure is defined in a .h file:
 *      - The definition of the structure xxx_s;
 *      - If the descriptor is public, an extern_st(st_xxx);
 *      - The definition of a macro public_st_xxx() or private_st_xxx()
 *      that creates the actual descriptor.
 * This convention makes the descriptor visible (if public) to any module
 * that can see the structure definition.  This is more liberal than
 * we would like, but it is a reasonable compromise between restricting
 * visibility and keeping all the definitional elements of a structure
 * together.  We require that there be no other externs for (public)
 * structure descriptors; if the definer of a structure wants to make
 * available the ability to create an instance but does not want to
 * expose the structure definition, it must export a creator procedure.
 */
/*
 * If the structure is defined in a .c file, we require that the following
 * appear together:
 *      - The definition of the structure xxx_s;
 *      - The gs_private_st_xxx macro that creates the descriptor.
 * Note that we only allow this if the structure is completely private
 * to a single file.  Again, the file must export a creator procedure
 * if it wants external clients to be able to create instances.
 *
 * Some structures are embedded inside others.  In order to be able to
 * construct the composite pointer enumeration procedures, for such
 * structures we must define not only the st_xxx descriptor, but also
 * a st_xxx_max_ptrs constant that gives the maximum number of pointers
 * the enumeration procedure will return.  This is an unfortunate consequence
 * of the method we have chosen for implementing pointer enumeration.
 *
 * Some structures may exist as elements of homogenous arrays.
 * In order to be able to enumerate and relocate such arrays, we adopt
 * the convention that the structure representing an element must be
 * distinguished from the structure per se, and the name of the element
 * structure always ends with "_element".  Element structures cannot be
 * embedded in other structures.
 *
 * Note that the definition of the xxx_s structure may be separate from
 * the typedef for the type xxx(_t).  This still allows us to have full
 * structure type abstraction.
 *
 * Descriptor definitions are not required for structures to which
 * no traceable pointers from garbage-collectable space will ever exist.
 * For example, the struct that defines structure types themselves does not
 * require a descriptor.
