_execl() funcution on windows 10 platform to rename the process

The _execl() function you mentioned is not available on Windows platforms. It is a POSIX function typically used in Unix-like operating systems.

On Windows, you can use the SetProcessName function from the Windows API to rename the current process. However, this function is not directly available in the Win32 API. You can achieve process renaming by modifying the process name in the process environment block (PEB) using some low-level techniques.

Here's an example of how you can rename the current process on Windows using C++:

cppCopy code
#include <Windows.h>

#include <string>



void SetProcessName(const std::wstring& newName)

{

    // Get the current process handle

    HANDLE hProcess = GetCurrentProcess();



    // Open the process with all access rights

    HANDLE hProcessDup;

    DuplicateHandle(hProcess, hProcess, hProcess, &hProcessDup, 0, FALSE, DUPLICATE_SAME_ACCESS);



    // Get the PEB address

    void* pPeb = nullptr;

    NTSTATUS status = NtQueryInformationProcess(hProcessDup, ProcessBasicInformation, &pPeb, sizeof(pPeb), nullptr);



    if (status != STATUS_SUCCESS)

    {

        // Handle error

        CloseHandle(hProcessDup);

        return;

    }



    // Get a pointer to the PEB

    PROCESS_BASIC_INFORMATION pbi;

    ReadProcessMemory(hProcessDup, pPeb, &pbi, sizeof(pbi), nullptr);



    // Get a pointer to the process parameters in the PEB

    void* pProcessParameters = nullptr;

    ReadProcessMemory(hProcessDup, pbi.PebBaseAddress + offsetof(PEB, ProcessParameters), &pProcessParameters, sizeof(pProcessParameters), nullptr);



    // Get a pointer to the image name in the process parameters

    UNICODE_STRING imageName;

    ReadProcessMemory(hProcessDup, pProcessParameters + offsetof(RTL_USER_PROCESS_PARAMETERS, ImagePathName), &imageName, sizeof(imageName), nullptr);



    // Modify the image name

    std::wstring newImagePath(newName);

    WriteProcessMemory(hProcessDup, imageName.Buffer, newImagePath.data(), newImagePath.size() * sizeof(wchar_t), nullptr);



    // Clean up

    CloseHandle(hProcessDup);

}



int main()

{

    // Set the new process name

    std::wstring newName = L"MyNewProcessName";

    SetProcessName(newName);



    // Continue with the rest of the program...



    return 0;

}

Please note that this code uses low-level Windows API functions and techniques. It involves reading and writing memory in the process address space and requires appropriate privileges and permissions. Make sure to handle errors and validate the success of each operation appropriately.

Additionally, modifying the process name in this way is not a standard or recommended practice on Windows and may have unintended consequences or compatibility issues.
