// bits for declaring and defining typed arrays

/*
 * Usage:
 *
 * DECLARRAY_BYTYPE(foo, bar, INLINE) declares "struct foo", which is
 * an array of pointers to "bar", plus the operations on it.
 *
 * DECLARRAY(foo, INLINE) is equivalent to
 * DECLARRAY_BYTYPE(fooarray, struct foo, INLINE).
 *
 * DEFARRAY_BYTYPE and DEFARRAY are the same as DECLARRAY except that
 * they define the operations.
 *
 * The argument INLINE can be used as follows:
 *
 * 1. For no inlining:
 *    In foo.h:
 *           DECLARRAY(foo, );
 *    In foo.c:
 *           DEFARRAY(foo, );
 *
 * 2. To be file-static:
 *    In foo.c:
 *           DECLARRAY(foo, static);
 *           DEFARRAY(foo, static);
 *
 * 3. To inline using C99:
 *    In foo.h:
 *           DECLARRAY(foo, inline);
 *           DEFARRAY(foo, inline);
 *
 * 4. To inline with old gcc:
 *    In foo.h:
 *           #ifndef FOO_INLINE
 *           #define FOO_INLINE extern inline
 *           #endif
 *           DECLARRAY(foo, );
 *           DEFARRAY(foo, FOO_INLINE);
 *    In foo.c:
 *           #define FOO_INLINE
 *           #include "foo.h"
 *
 * 5. To inline such that it works both with old gcc and C99:
 *    In foo.h:
 *           #ifndef FOO_INLINE
 *           #define FOO_INLINE extern inline
 *           #endif
 *           DECLARRAY(foo, FOO_INLINE);
 *           DEFARRAY(foo, FOO_INLINE);
 *    In foo.c:
 *           #define FOO_INLINE
 *           #include "foo.h"
 *
 * The mechanism in case (4) ensures that an externally linkable
 * definition exists.
