如何解决JNA错误“仅发出部分ReadProcessMemory或WriteProcessMemory请求”？

如何解决如何解决JNA错误“仅发出部分ReadProcessMemory或WriteProcessMemory请求”？

我试图用Java编写一个小培训师，但是我被困在ReadProcessMemory中。我在项目中使用JNA和JNA平台v5.6.0。当我尝试以此方式读取ProcessMemory时

Psapi.MODULEINFO moduleinfo = process.getModuleInfo("ac_client");
long base_address = Pointer.nativeValue(moduleinfo.lpBaSEOfDll);

int player = process.readInt32(base_address + player_ptr);

我有此错误：

仅发出了ReadProcessMemory或WriteProcessMemory请求的一部分。

基地址和player_ptr是正确的地址。我在互联网上看到的所有ReadProcessMemory示例都没有将指针作为内存地址的参数。

这是我的全班课。

   private final HANDLE process;

    private BProcess(HANDLE process) {
        this.process = process;
    }

    public static BProcess open(String name) {
        WinDef.HWND window = User32.INSTANCE.FindWindow(null,name);

        IntByReference i_ref = new IntByReference();

        User32.INSTANCE.GetwindowThreadProcessId(window,i_ref);

        HANDLE process = Kernel32.INSTANCE.OpenProcess(WinNT.PROCESS_VM_READ | WinNT.PROCESS_VM_OPERATION | WinNT.PROCESS_VM_WRITE,false,i_ref.getValue());

        return new BProcess(process);
    }

    public int readInt32(long address) {
        Pointer buffer = new Memory(4);
        Pointer p_address = new Memory(8);

        p_address.setLong(0,address);

        IntByReference iref = new IntByReference();

        boolean b = Kernel32.INSTANCE.ReadProcessMemory(this.process,p_address,buffer,4,iref);

        if (!b) {
            System.out.println(p_address.getLong(0));
            throw new Win32Exception(Native.getLastError());
        }

        return ByteBuffer.wrap(buffer.getByteArray(0,4)).get();
    }

    public Psapi.MODULEINFO getModuleInfo(String name) {
        WinDef.HMODULE[] hmodules = new WinDef.HMODULE[400];
        IntByReference i_ref = new IntByReference();
        boolean b = Psapi.INSTANCE.EnumProcessModules(this.process,hmodules,hmodules.length,i_ref);

        if (!b) {
            throw new Win32Exception(Native.getLastError());
        }

        WinDef.HMODULE module = null;
        int i = 0;

        while ((module = hmodules[i]) != null) {

            char[] c = new char[500];
            Psapi.INSTANCE.GetmodulefileNameExW(this.process,module,c,500);
            System.out.println(new String(c));

            String moduleName = new String(c);

            if (moduleName.contains(name)) {
                break;
            }
            i++;
        }

        if (module == null) {
            throw new NoSuchElementException(name);
        }

        Psapi.MODULEINFO moduleinfo = new Psapi.MODULEINFO();

        Psapi.INSTANCE.GetModuleinformation(this.process,moduleinfo,moduleinfo.size());

        return moduleinfo;
    }

    public void close() {
        Kernel32.INSTANCE.CloseHandle(this.process);
    }
