根据pid获得路径 2006-10-25 19:28

这是编写kill process时用到的

BOOL GetProcessModule(DWORD dwPID, DWORD dwModuleID, LPMODULEENTRY32 lpMe32, DWORD cbMe32)
{
 BOOL          bRet        = FALSE;
    BOOL          bFound      = FALSE;
    HANDLE        hModuleSnap = NULL;
    MODULEENTRY32 me32        = {0};
 
    hModuleSnap = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, dwPID);
    if (hModuleSnap == INVALID_HANDLE_VALUE)
        return (FALSE);
 
    me32.dwSize = sizeof(MODULEENTRY32);
 
    if (Module32First(hModuleSnap, &me32))
    {
        do
        {
            if (me32.th32ModuleID == dwModuleID)
            {
                CopyMemory (lpMe32, &me32, cbMe32);
                bFound = TRUE;
            }
        }
        while (!bFound && Module32Next(hModuleSnap, &me32));
  
        bRet = bFound;  
    }
    else
        bRet = FALSE;
 
    CloseHandle (hModuleSnap);
 
    return (bRet);
}

PCHAR ProcessPidToPath(DWORD ProcessId, PCHAR ProcessName)
{
 PROCESSENTRY32 processEntry = { 0 };
 processEntry.dwSize = sizeof(PROCESSENTRY32);
 
 lstrcpy(ProcessName, "");
 HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
 if (hProcessSnap == INVALID_HANDLE_VALUE)
 {
  printf("Failed to take process snapshot. Process names will not be shown.\n\n");
 }
 if (!Process32First(hProcessSnap, &processEntry))
 {
  return ProcessName;
 }
 
 do
 {
  if (processEntry.th32ProcessID == ProcessId)
  {
   MODULEENTRY32 me32 = {0};
   GetProcessModule(processEntry.th32ProcessID,
    1, &me32, sizeof(MODULEENTRY32));
   
   if (lstrlen(me32.szExePath) != 0)
   {
    lstrcpy(ProcessName, me32.szExePath);
   }
   else
   {
    lstrcpy(ProcessName, processEntry.szExeFile);
   }
   return ProcessName;
  }

 } while(Process32Next(hProcessSnap, &processEntry));

 CloseHandle(hProcessSnap);
 return ProcessName;
}
