c++ 没学好要转换一段代码！struct 转record

翻译这段代码也不用学好C++，会一点点就行了。public driver:^nfc_driver;
nfc_driver 这个record 你定义了没有，代码在哪里

/**
* NFC device
*/
typedef struct nfc_device nfc_device;/**
* NFC device driver我就巨晕！自己定义自己的别名！

nfc-types.h
里的定义！但有点怪！
  * NFC device
  */
typedef struct nfc_device nfc_device; /**
  * NFC device driver
nfc-internal.hstruct nfc_device {
   const nfc_context *context;
   const struct nfc_driver *driver;
   void *driver_data;
   void *chip_data;   /** Device name string, including device wrapper firmware */
   char    name[DEVICE_NAME_LENGTH];
   /** Device connection string */
   nfc_connstring connstring;
   /** Is the CRC automaticly added, checked and removed from the frames */

       selecting tags supporting it? */

};括号表示啥？

size_t (*scan)(const nfc_context *context, nfc_connstring connstrings[], const size_t connstrings_len);是不是 = function scan(nfc_context：context, nfc_connstring:connstrings[], size_t connstrings_len:DWORD);

struct nfc_device *(*open)(const nfc_context *context, const nfc_connstring connstring); 这行应该是返回值是个nfc_device？

function initiator_target_is_present(pnd:Tpnd;pnt:pnfc_target):Integer;
//   int (*target_init)(struct nfc_device *pnd, nfc_target *pnt, uint8_t *pbtRx, const size_t szRx, int timeout);
  function target_init(pnd:Tpnd;pnt:pnfc_target;pbtRx:^Byte;szRx:DWORD;timeout:Integer):Integer;
  //  int (*target_send_bytes)(struct nfc_device *pnd, const uint8_t *pbtTx, const size_t szTx, int timeout);
  function target_send_bytes(pnd:Tpnd;pbtTx:^Byte;szTx:DWORD;timeout:Integer):Integer;
  // int (*target_receive_bytes)(struct nfc_device *pnd, uint8_t *pbtRx, const size_t szRxLen, int timeout);
  function target_receive_bytes(pnd:Tpnd;pbtRx:^Byte;szRxLen:DWORD;timeout:Integer):Integer;
//  int (*target_receive_bits)(struct nfc_device *pnd, uint8_t *pbtRx, const size_t szRxLen, uint8_t *pbtRxPar);
  function target_receive_bits(pnd:Tpnd;pbtRx:^Byte;szRxLen:DWORD;pbtRxPar:^Byte):Integer;
//   int (*device_set_property_bool)(struct nfc_device *pnd, const nfc_property property, const bool bEnable);
  function device_set_property_bool(pnd:Tpnd;Pproperty:nfc_property;bEnable:boolean):Integer;
// int (*device_set_property_int)(struct nfc_device *pnd, const nfc_property property, const int value);
  function device_set_property_int(pnd:Tpnd;Pproperty:nfc_property;value;Integer):Integer;
// int (*get_supported_modulation)(struct nfc_device *pnd, const nfc_mode mode, const nfc_modulation_type **const supported_mt);
**const supported_mt的是一个静态指针的指针！
