Convert "C Function Pointer" to D?

[Robert]

Hi, I have something like this:

struct ext_api {
	int version;
	void *(*make_block)(u32 size);
	void *(*make_string)(u32 size, int uni);
	u32 *(*map_words)(REBSER *ser);
	u32 (*find_word)(u32 *words, u32 word);
	int (*series_info)(REBSER *ser, REBCNT what);
	int (*get_char)(REBSER *ser, u32 index);
	u32 (*set_char)(REBSER *ser, u32 index, u32 chr);
	int (*get_value)(REBSER *ser, u32 index, RXIARG *val);
	int (*set_value)(REBSER *ser, u32 index, RXIARG val, int type);
	int (*get_string)(REBSER *ser, u32 index, void **str);
}

How do I convert such a struct to D? I will get a ext_api pointer from 
a C compiled program and use this pointer via the struct to call the C 
functions.
