Iswow64process2 Windows 7

[Qiana Thieklin]

Thethree paramaters for the function getBits are all BOOLs. The passed arguments will be set to TRUE or FALSE after theappropriate information is extracted in the function. Since the parameters are all reference types, changing them to the appropriatevalues in the function changes the values in the original arguments passed in by the caller so the caller can use them. The functionreturns a BOOL which is TRUE if the function completed successfully, FALSE otherwise.

Their names are a bit confusing because of the word Machine in both: these parameters do not necessarily reflect the physical machine architecture(i.e., the type of physical processor hardware of the machine), but the architecture of the process itself (ProcessMachine) and the architectureof the host Windows operating system (NativeMachine).

If it is not IMAGE_FILE_MACHINE_UNKNOWN, it will be set to a value that reveals the type of the WOW64 process:see here. There are many different machine type constants, some referring to 64 bit architectures,and some architectures that are no longer supported by Windows versions that have IsWow64Process2.Note this qoute from these docs:

These constants would indicate a 32 bit x86 process or a 32 bit ARM process, respectively. Note that an x86 process can run under eitheran AMD64 or ARM64 WOW64 emulator, but a 32 bit ARM process can only run under an ARM64 WOW64 emulator.

NativeMachine will return a value indicating the architecture type of the host Windows operating systemThat value is also an image file machine constant. As best I can tell from research, the possible values,which would be for Windows architectures supporting the IsWow64Process2 API, are:

IsWow64Process2 will return TRUE if it succeeds, otherwise, FALSE. If it fails, I display an error indication that includes thelast error code returned by GetLastError giving the reason for the failure (see here and here). I then returnFALSE to indicate failure to the caller, in which case the three BOOL arguments will have undefined values.

The above code fragment notices the process is not running under WOW64 since IMAGE_FILE_MACHINE_UNKNOWN is returned (see above).It immediately sets isWOW64 to FALSE. The following three paths run under this conditional block:

If NativeMachine is any of the possible 64 bit values, indicating the host Windows architecture is 64 bit, I set windowsIs32Bit andprocessIs32Bit to FALSE and return success. Since we know Windows is 64 bit, and the process is not running under WOW64,we know the process is running 64 bit natively on the host OS.

If NativeMachine is any of the possible 32 bit values, indicating the host Windows architecture is 32 bit, I set windowsIs32Bit andprocessIs32Bit to TRUE and return success. Since we know Windows is 32 bit, we know the process is running 32 bit natively on the host OS.A 64 bit process cannot run under 32 bit Windows.

Finally, if ProcessMachine did not return IMAGE_FILE_MACHINE_UNKNOWN, the process is running under WOW64. windowsIs32Bit is set to FALSE becauseWOW64 is only possible under 64 bit Windows, isWow64 is set TRUE, and processIs32Bit is set TRUE because only a 32 bit processcan run under WOW64.

The usage is quite straightforward. In the example, we define the three BOOL variables to pass as arguments then call the function getBitsto fill them with the appropriate values. If getBits returns FALSE, we exit the process with a return from main with the value -1to indicate failure.

IsWow64Process2 provides a nice, new API for its supported Windows versions that returns more information than the old IsWow64Process(see here). There is no need to fuss about old architectures no longer supported in the latest versions of Windows,and it is a great way to figure out what the Windows host machine architecture is.

I have written this to provide hopefully robust, working example code of its usage for the community, which I could not find elsewhere.Even though I researched heavily, I am still unsure of some of the details, which I note above, and could not exercise all codepaths. However, I feel as is there is great value. Feel free to explore on your own using what I have done as a launching point.

Package windows contains an interface to the low-level operating systemprimitives. OS details vary depending on the underlying system, andby default, godoc will display the OS-specific documentation for the currentsystem. If you want godoc to display syscall documentation for anothersystem, set $GOOS and $GOARCH to the desired system. For example, ifyou want to view documentation for freebsd/arm on linux/amd64, set $GOOSto freebsd and $GOARCH to arm.

Hi everyone! I use windows 7 64-bit, and when I try to install an app (for example WhatsApp), I get this error: Kernel32.dll entry not point error. The procedure entry point SetDefaultdllDirectories could not be located kernel32.dll. What am I doing now?

What is Kernel32.dll? It is an important DLL file in the Microsoft Windows system. As a Windows KT Base API Client DLL file, the real kernel32 dll file is a 32-bit dynamic link library file used by the Windows system to manage system memory, interrupts, input/output operations, synchronization, and process.

What causes the entry point not found kernel32.dll Windows XP error? As the error message suggested, the error is often related to a corrupted or missing kernel32.dll file. To be specific, virus infection, power outage, hard drive errors, corrupted system files, and outdated device drivers can cause the kernel32 dll missing error.

In addition, you can try replacing the corrupted kernel32.dll with a new one via Microsoft Windows setup CD/DVD. If you have a Windows installation media, you can follow the steps below to recover the dll file.

Step 2. Type the sfc /scannow command in the elevated command prompt and hit Enter. After that, the SFC tool will scan and try to repair the corrupted system files automatically.

Step 2. You will receive a message saying Check your computer for memory problems. Here are 2 options for you to perform a RAM test. It is recommended that you click Restart now and check for problems.

Step 3. Then your computer will restart and Windows Memory Diagnostics Tool will automatically perform the RAM test. This process may take you some time. You can see the overall test status bar and the detected problems during this process.

If none of the above methods fix the entry point not found kernel32 dll Windows XP/7/8/10 error, you may need to perform a clean installation of Windows. By doing so, your system will revert to its original status, which can clear the kernel32.dll.error.

Here comes the end of this post. If you have better solutions to the kernel32.dll error, please share them with us in the following comment zone.
