Question

Let\'s say that on the C++ side my function takes a variable of type jstring named myString. I can convert it to an ANSI string as follows:

And who frees wsz? I would recommend STL!

std::wstring JavaToWSZ(JNIEnv* env, jstring string)
{
    std::wstring value;
    if (string == NULL) {
        return value; // empty string
    }
    const jchar* raw = env->GetStringChars(string, NULL);
    if (raw != NULL) {
        jsize len = env->GetStringLength(string);
        value.assign(raw, len);
        env->ReleaseStringChars(string, raw);
    }
    return value;
}
