    如题，我有一个 C 的 .so, 里面有一个函数是注册回调的。 类似于

    #ifndef __TEST_H__ #define __TEST_H__ #ifdef __cplusplus extern "C"{ #endif #define API __attribute__((visibility("default"))) typedef struct info{ int a; }tInfo; typedef int(*cb) (tInfo* n); API int setcallback(cb s); #ifdef __cplusplus } #endif #endif

    现在我想在 Go 里面通过 Cgo 调用setcallback，我要怎么做呢？ 看了半天资料 还是看不懂。。

  • 函数
  • endif
  • int
  • ifdef
