我正在尝试获取 C++ 中任何正在运行的进程的文件句柄。这是我的代码:
#include <windows.h>
#include <process.h>
#include <Tlhelp32.h>
#include <winbase.h>
#include <string.h>
void killProcessByName(const char *filename)
{
HANDLE hSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPALL, NULL);
PROCESSENTRY32 pEntry;
pEntry.dwSize = sizeof (pEntry);
BOOL hRes = Process32First(hSnapShot, &pEntry);
while (hRes)
{
if (strcmp(pEntry.szExeFile, filename) == 0)
{
HANDLE hProcess = OpenProcess(PROCESS_TERMINATE, 0,
(DWORD) pEntry.th32ProcessID);
if (hProcess != NULL)
{
CloseHandle(hProcess);
}
}
hRes = Process32Next(hSnapShot, &pEntry);
}
CloseHandle(hSnapShot);
}
int main()
{
killProcessByName("WINWORD.EXE");
return 0;
}
代码工作正常,但没有释放所需的句柄。比较 ( strcmp
) 部分有问题吗?还是我做错了什么?
