我有一个 ac 库，我想用 python 2.7 ctypes 包装。

typedef struct SRSLTE_API{
  void *ptr;
  uint32_t R;
  uint32_t K;
  uint32_t framebits;
  bool tail_biting;
  float gain_quant; 
  int16_t gain_quant_s; 
  int (*decode) (void*, uint8_t*, uint8_t*, uint32_t);
  int (*decode_f) (void*, float*, uint8_t*, uint32_t);
  void (*free) (void*);
  uint8_t *tmp;
  uint8_t *symbols_uc;
}srslte_viterbi_t;

如何在 python 中创建这个结构？这就是我目前所拥有的。

from ctypes import *
class srslte_viterbi_t(Structure):
    _fields_ = [("ptr", c_void_p),
                ("R", c_uint),
                ("K", c_uint),
                ("framebits", c_uint),
                ("tail_biting", c_bool),
                ("gain_quant", c_float),
                ("gain_quant_s", c_short),
                ("decode", POINTER(c_int)),
                ("decode_f", POINTER(c_int)),
                ("free", c_void_p),
                ("tmp", POINTER(c_ubyte)),
                ("symbols_uc", POINTER(c_ubyte))
                ] …
