Is there any function in psapi or windows.h to get desired process\' is running via only the process name (e.g : \"chrome.exe\") without getting all processes.

#include "stdafx.h"

using namespace std;

DWORD FindProcessId(const std::wstring& processName);

int main(int argc, char* argv[])
{

  bool bAnyBrowserIsOpen = false;

  if ( FindProcessId(L"chrome.exe") || FindProcessId(L"firefox.exe") || FindProcessId(L"iexplore.exe"))
  {
     bAnyBrowserIsOpen = true;
  }

  return 0;
}


DWORD FindProcessId(const std::wstring& processName)
{
  PROCESSENTRY32 processInfo;
  processInfo.dwSize = sizeof(processInfo);

  HANDLE processesSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
  if ( processesSnapshot == INVALID_HANDLE_VALUE )
    return 0;

  Process32First(processesSnapshot, &processInfo);
  if ( !processName.compare(processInfo.szExeFile) )
  {
    CloseHandle(processesSnapshot);
    return processInfo.th32ProcessID;
  }

  while ( Process32Next(processesSnapshot, &processInfo) )
  {
    if ( !processName.compare(processInfo.szExeFile) )
    {
      CloseHandle(processesSnapshot);
      return processInfo.th32ProcessID;
    }
  }

  CloseHandle(processesSnapshot);
  return 0;
}
