C++ Process32Next only returns 相同的进程

Question

我一直在尝试开发一个 C++ 库，目的是仅通过名称来终止进程。正如某处所述，我必须做一个系统快照，然后列出每个进程（通过它的 ID），打开进程并检查它的文件名是否与传递给函数的文件名相同，如果是，则终止它。

这是我的代码： main.cpp

#include <iostream>
#include "proman.hpp"
using namespace std;

int main(int argc, char* argv[])
{
    cout << "INIT PRUBA" << endl;
    cout << "Trying to kill cmd.exe" << endl;
    const TCHAR* proc = L"cmd.exe";
    killPBN(proc);
    getchar(); getchar();
    return 0;
}

proman.hpp

#ifndef INC_PROMAN_H
#define INC_PROMAN_H


#include <TCHAR.h> //http://www.codeproject.com/Articles/76252/What-are-TCHAR-WCHAR-LPSTR-LPWSTR-LPCTSTR-etc
#include <windows.h>
#include <tlhelp32.h>
#include <iostream>
#include "proman.cpp"
//Function prototypes

bool killPBN(const TCHAR *procname); 



#endif

proman.cpp

bool killPBN(const TCHAR *procname)//
{
    //Compiles, but doesnt work, probablemente el fallo este en el compare dentro del for(;;) ==
    //Init some stuff
    TCHAR processPath[MAX_PATH];
    DWORD processId;
    HANDLE tmpHandle = NULL;
    BOOL b;
    
    //Handle to store the snapshot
    HANDLE systemSnap;
    //Initialize to every process dump (no heap nor modules)
    systemSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
    if (systemSnap==INVALID_HANDLE_VALUE)
    {
        std::cout << "Can't snap system" << std::endl;
        throw(NULL);
    }
    
    //We have our snapshot, we need to enumerate every process (get its ID)
    //A custom handle to store process data
    PROCESSENTRY32 procHandler;
    //Initialize dwSize so Process32First won't fail
    procHandler.dwSize = sizeof(PROCESSENTRY32);
    //We are ready to call Process32First
    Process32First(systemSnap, &procHandler);
    //Got our first process, now, dump it's ID and ExeFile
    //processPath = procHandler.szExeFile; //Exe Path
    //processId   = procHandler.th32ProcessID; //PID
    
    std::cout << "First Proc: " << procHandler.szExeFile << std::endl;
    
    if (procHandler.szExeFile == procname) //parameter here, use strncompare o como sea
    {
        //Try to open process
        tmpHandle = OpenProcess(PROCESS_ALL_ACCESS, TRUE, procHandler.th32ProcessID);
        //If opened, kill process
        if (NULL != tmpHandle)
        {   
            std::cout << "Killing: " << procHandler.szExeFile << std::endl;
            TerminateProcess(tmpHandle, 0);
            return 0; 
        }
        //If not opened, throw expection of no admin rights
        else
        {
            //no admin rights?
            //throw(std::out_of_range); 
            std::cout << "Can't Kill Proc: " << procHandler.szExeFile << std::endl;
        }
    }
    else
    {
        while(1==1)
        {
            //The process wasn't the one we were looking for, look next
            b = Process32Next(systemSnap, &procHandler);
            if (b==FALSE)
            {/*throw(proc_not_found);*/
                std::cout << "No more processes" << std::endl;
                break;
            } //no deberia hacer throw, eso solo si hay un error, aqui usar un return!!! si no hay mas procesos
            else
            {
                if (procHandler.szExeFile == procname)
                {
                    tmpHandle = OpenProcess(PROCESS_ALL_ACCESS, TRUE, procHandler.th32ProcessID);
                    if (NULL != tmpHandle)
                    {   
                        TerminateProcess(tmpHandle, 0);
                    }
                }
                else
                {
                    std::cout << "Can't kill " << procHandler.szExeFile <<std::endl;
                    //throw(std::out_of_range); //no admin rights?
                }   
            }
        }   
                
    }
    std::cout << " Exit Success";
    

    //Deletes snapshot and tmpHandle
    CloseHandle(systemSnap);
    CloseHandle(tmpHandle);
    return 0;
    
}

我知道的代码有点大。这个想法是寻找第一个过程，如果不是所需的过程，请寻找下一个过程。但是，这是输出：

INIT PRUBA
Trying to  kill cmd.exe
First Proc: 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
Can't kill 00C1F510
...
No more processes
 Exit Success

如您所见，程序似乎没有比第一个进程读取更多。

感谢您的宝贵时间，

编辑：如您所见，szExeFile 应类似于 cmd.exe（exe 名称），但它可能是某种地址？

EDIT2：另外，请注意 TCHAR，根据编译器设置，它应该被 ANSI/UNICODE char/wchart 替换。

按照@BarmakShemirani 的说明，我将使用 Unicode 函数作为 wcout 或 wcscmp。谢谢。
