c++ - cdecl inet_ntop(int,void const *,char *,unsigned int)" 在函数 _main 中引用

Question

我在我的代码中使用 inet_ntop 来获取离线捕获文件的 IP 地址。我收到错误

error LNK2019: unresolved external symbol "char const*__cdecl inet_ntop(int,void const *,char *,unsigned int)" (?inet_ntop@@YAPBDHPBXPADI@Z) referenced in function _main
