将C char*转换为JNA中的java字符串

public interface CLibrary extends Library {
    CLibrary INSTANCE = (CLibrary) Native.loadLibrary("your_library_name", CLibrary.class);

}

import com.sun.jna.Memory;

public class Main {
    public static void main(String[] args) {
        String javaString = "Hello, World!";
        Pointer cString = convertCString(javaString);
        CLibrary.INSTANCE.your_c_function_name(cString);
    }

    private static Pointer convertCString(String javaString) {
        byte[] bytes = javaString.getBytes();
        Memory memory = new Memory(bytes.length + 1);
        memory.write(0, bytes, 0, bytes.length);
