C++ 风格从 unsigned char * 转换为 const char *

我有:

unsigned char *foo();
std::string str;
str.append(static_cast<const char*>(foo()));

错误:invalid static_cast from type ‘unsigned char*’ to type ‘const char*’

以 C++ 风格在此处进行转换的正确方法是什么?

What's the correct way to cast here in C++ style?

推荐答案

reinterpret_cast

reinterpret_cast
