我使用 DuplicateHandle 向子进程共享一个内核对象，我需要将该对象的句柄传输给该进程，该怎么做？

int main() {
    STARTUPINFO cif;
    ZeroMemory(&cif, sizeof(STARTUPINFO));
    PROCESS_INFORMATION pi;
    CreateProcess("sp.exe", NULL, NULL, NULL, FALSE, 0, NULL, NULL, 
    &cif, &pi);

    HANDLE Semaphore = CreateSemaphore(NULL, 0, 1, NULL);

    DuplicateHandle(GetCurrentProcess(), Semaphore, pi.hProcess, NULL, 
    DUPLICATE_SAME_ACCESS, FALSE, 0);

    WaitForSingleObject(Semaphore, INFINITE);
    cout << "Test3: access granted";

    CloseHandle(pi.hProcess);
    CloseHandle(Semaphore);
}
