如何在没有RtlInitUnicodeString的情况下设置PUNICODE_STRING？

#include <windows.h>

void SetUnicodeString(PUNICODE_STRING pString, PCWSTR pValue)
{
    WCHAR* pBuffer = new WCHAR[(wcslen(pValue) + 1) * sizeof(WCHAR)];
    wcscpy_s(pBuffer, wcslen(pValue) + 1, pValue);
    
    pString->Buffer = pBuffer;
    pString->Length = wcslen(pValue) * sizeof(WCHAR);
    pString->MaximumLength = (wcslen(pValue) + 1) * sizeof(WCHAR);
}

int main()
{
    UNICODE_STRING uString;
    SetUnicodeString(&uString, L"Hello, World!");

    // 使用uString进行操作
    
    delete[] uString.Buffer;

    return 0;
}
