使用c2hs与结构和匿名联合进行接口
使用c2hs与结构和匿名联合进行接口
提问于 2014-05-18 07:10:17
如何将这段C代码编码到.chs文件中，以便c2hs可以将其转换为相对较好的文件？
typedef enum {
MONOME_BUTTON_UP = 0x00,
MONOME_BUTTON_DOWN = 0x01,
MONOME_ENCODER_DELTA = 0x02,
MONOME_ENCODER_KEY_UP = 0x03,
MONOME_ENCODER_KEY_DOWN = 0x04,
MONOME_TILT = 0x05,
/* update this if you add event types */
MONOME_EVENT_MAX = 0x06
} monome_event_type_t;
typedef struct monome monome_t; /* opaque data type */
typedef struct monome_event monome_event_t;
typedef void (*monome_event_callback_t)
(const monome_event_t *event, void *data);
struct monome_event {
monome_t *monome;
monome_event_type_t event_type;
/* __extension__ for anonymous unions in gcc */
__extension__ union {
struct {
unsigned int x;
unsigned int y;
} grid;
struct {
unsigned int number;
int delta;
} encoder;
struct {
unsigned int sensor;
int x;
int y;
int z;
} tilt;
};

这样如何:更改代码，以便命名成员。内存中的布局是相同的，因此它将是二进制兼容的。您必须为lib的每个版本安装此补丁。
struct monome_event {
monome_t *monome;
monome_event_type_t event_type;
/* __extension__ for anonymous unions in gcc */
__extension__ union {
struct me_grid {
unsigned int x;
unsigned int y;
} grid;
struct me_encoder {
unsigned int number;
int delta;
} encoder;
struct me_tilt {
unsigned int sensor;
int x;
int y;
int z;
} tilt;
};
