有没有办法传递一个std ::字符串到接受一个char *并更改其内容的函数？ [英] Is there any way to pass a std::string to a function that accepts a char* and changes its contents?

问题描述

我想回到编程，特别是控制台游戏。我听说诅咒是好的，所以我找到了一个curses教程，我进入了。我使用C ++，当然我想利用std :: string，但函数 getstr（）只接受char *。有什么方法可以传递一个字符串作为char *，或者我必须放弃使用C ++字符串？

I'm trying to get back into programming, specifically console games. I'd heard that curses was good for that, so I found a curses tutorial and I'm getting into that. I'm using C++, and naturally I wanted to take advantage of std::string, but functions like getstr() only accept char*. Is there any way to pass a string as a char*, or am I gonna have to forgo using C++ strings?

推荐答案

仍然可以使用C ++ std :: string ，但是你必须将内容复制到缓冲区中（ std :: vector< char> code>将是好的），并使用期望可写入 char * 缓冲区的函数时将其复制回来。

You can still use C++ std::string, but you'll have to copy the contents into a buffer (std::vector<char> would be good) and copy it back when using functions that expect a writable char* buffer.
