CMutablePointer< CString>快速转换为字符串 [英] CMutablePointer<CString> to String in swift-language

问题描述

我有一个库，其功能如下：

I have a library which has a function like this:

int get_user_name(const char **buffer);

快速调用，应该像这样：

in swift, should call like this:

var name:CMutablePointer<CString> = nil
get_user_name(name)

我想使此功能使用起来更舒适，所以我包装了

I want make use this function more comfortable so I wrapped this up:

func get_username() -> String {
    var name:CMutablePointer<CString> = nil
    get_user_name(name)

    // how to convert name to String
}

我的问题是如何将名称转换为字符串

I question is how to convert name to String

推荐答案

它类似于：

 var stringValue :CString = ""

 name.withUnsafePointer {p in
      stringValue = p.memory
 }

 return NSString(CString: stringValue)
