如何在Kotlin/Native中将const char *转换为KString? [英] How to convert const char* to KString in Kotlin/Native?

问题描述

在C ++文件中，我想将const char *转换为KString，这样我就可以使用

In a C++ file, I want to convert a const char* to KString, so that I can then pass the KString to a Kotlin file using Kotlin/Native.

我相信答案就在于功能

    OBJ_GETTER(utf8ToUtf16, const char* rawString, size_t rawStringLength)

我在 KString中找到的

.cpp .但是，即使我在

that I found in KString.cpp. But even though I discovered the used define statements in Memory.h, I have not yet managed to properly call the function utf8ToUtf16 from my own C++ file to get a KString. Any help is appreciated.

推荐答案

这取决于您如何与Kotlin代码进行交互.如果使用-produce dynamic生成动态库，则字符串将自动转换，例如，参见

It depends on how you want to interact with Kotlin code. If you produce dynamic library with -produce dynamic, then string are converted automatically, see for example https://github.com/JetBrains/kotlin-native/blob/adf8614889e8cf5038a79960aa9651ca7d45e409/samples/python_extension/src/main/c/kotlin_bridge.c#L72. So no additional magic is required at all. Same with Objective-C strings and -produce framework. And for other cases, there shall be no need to pass strings C -> Kotlin (callbacks produced with staticCFunction also do autoconversion).
