How can I find a process by name and kill using ctypes?
提问by Synapse
On Windows, I want to find a process by the name of 'exename.exe', and then kill it.
在 Windows 上，我想找到一个名为“exename.exe”的进程，然后将其杀死。
How can I do it by ctypes not any other 3rd-party module?
我如何通过 ctypes 而不是任何其他 3rd 方模块来做到这一点？

Try this:
尝试这个：
import sys, os.path, ctypes, ctypes.wintypes
Psapi = ctypes.WinDLL('Psapi.dll')
EnumProcesses = Psapi.EnumProcesses
EnumProcesses.restype = ctypes.wintypes.BOOL
GetProcessImageFileName = Psapi.GetProcessImageFileNameA
GetProcessImageFileName.restype = ctypes.wintypes.DWORD
Kernel32 = ctypes.WinDLL('kernel32.dll')
OpenProcess = Kernel32.OpenProcess
OpenProcess.restype = ctypes.wintypes.HANDLE
TerminateProcess = Kernel32.TerminateProcess
TerminateProcess.restype = ctypes.wintypes.BOOL
CloseHandle = Kernel32.CloseHandle
MAX_PATH = 260
PROCESS_TERMINATE = 0x0001
PROCESS_QUERY_INFORMATION = 0x0400
count = 32
while True:
ProcessIds = (ctypes.wintypes.DWORD*count)()
cb = ctypes.sizeof(ProcessIds)
BytesReturned = ctypes.wintypes.DWORD()
if EnumProcesses(ctypes.byref(ProcessIds), cb, ctypes.byref(BytesReturned)):
if BytesReturned.value<cb:
break
else:
count *= 2
else:
sys.exit("Call to EnumProcesses failed")
for index in range(BytesReturned.value / ctypes.sizeof(ctypes.wintypes.DWORD)):
ProcessId = ProcessIds[index]
hProcess = OpenProcess(PROCESS_TERMINATE | PROCESS_QUERY_INFORMATION, False, ProcessId)
if hProcess:
ImageFileName = (ctypes.c_char*MAX_PATH)()
if GetProcessImageFileName(hProcess, ImageFileName, MAX_PATH)>0:
filename = os.path.basename(ImageFileName.value)
if filename == 'notepad.exe':
TerminateProcess(hProcess, 1)
CloseHandle(hProcess)

This may be cheating, but it works without even getting ctypes involved.
这可能是作弊，但它甚至不需要涉及 ctypes 就可以工作。
import subprocess
subprocess.call("taskkill /IM exename.exe")
taskkillis a Windows command; this is just invoking it through Python.
taskkill是一个 Windows 命令；这只是通过 Python 调用它。
