CのデータをRubyオブジェクトにする

Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして取り扱いたい場合がありえます．このような場合はTypedData_XXX マクロ群を用いて構造体へのポインタとRubyのオブジェクトとを互いに変換できます．

# 古い(非Typedな)Data_XXXマクロ群は非推奨になりました．

# 将来のバージョンのRubyでは古いマクロは動作しなくなる可能性があります．

#include <stdio.h>

#define IS_ARRAY(ary) ((void*)(ary) == (void*)&(ary))
#define TEST(ary, expected) \
  printf( \
      "%s:%u: expected %s, actually %s\n", \
      __FILE__, \
      __LINE__, \
      expected, \
      (IS_ARRAY(ary) ? "array" : "ptr"))

On the 6th of May, 1709, I took a solemn leave of his majesty, and
all
my friends.  This prince was so gracious as to order a guard to
conduct me to Glanguenstald, which is a royal port to the south-
west part of the island.  In six days I found a vessel ready to
carry me to Japan, and spent fifteen days in the voyage.
