Subject: wrapping a C struct[] constant

I have some C code with a struct definition

struct flag_str {
	unsigned int val;
	const char *str;
};

and an inline array

struct flag_str extent_flags[] = {
	{ FIEMAP_EXTENT_LAST,		"last" },
	{ FIEMAP_EXTENT_UNKNOWN,	"unkown" },
	{ FIEMAP_EXTENT_DELALLOC,	"delalloc" },
	{ FIEMAP_EXTENT_NO_BYPASS,	"no_bypass" },
	{ FIEMAP_EXTENT_SECONDARY,	"secondary" },
	{ FIEMAP_EXTENT_NET,		"net" },
	{ FIEMAP_EXTENT_DATA_COMPRESSED, "data_compressed" },
	{ FIEMAP_EXTENT_DATA_ENCRYPTED, "data_encrypted" },
	{ FIEMAP_EXTENT_NOT_ALIGNED,	"not_aligned" },
	{ FIEMAP_EXTENT_DATA_INLINE,	"data_inline" },
	{ FIEMAP_EXTENT_DATA_TAIL,	"data_tail" },
	{ FIEMAP_EXTENT_UNWRITTEN,	"unwritten" },
	{ FIEMAP_EXTENT_MERGED,		"merged" },
	{ 0,				NULL },
};

What's the simplest way to expose that array as a ruby constant (other
than just copy/pasting the data, of course :))?
