以下是 Windows API 函数的 C 语言代码示例,用于遍历所有 "wechat.exe" 进程,获取类型为 "mutant" 的句柄,并关闭该句柄:
```
#include <Windows.h>
#include <TlHelp32.h>
#include <string.h>
int main()
{
HANDLE hProcessSnap;
HANDLE hProcess;
PROCESSENTRY32 pe32;
HANDLE hMutant;
DWORD dwPriorityClass;
// 创建进程快照
hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (hProcessSnap == INVALID_HANDLE_VALUE)
{
printf("CreateToolhelp32Snapshot failed. Error code: %d\n", GetLastError());
return 1;
}
// 设置结构体的大小
pe32.dwSize = sizeof(PROCESSENTRY32);
// 获取第一个进程的信息
if (!Process32First(hProcessSnap, &pe32))
{
printf("Process32First failed. Error code: %d\n", GetLastError());
CloseHandle(hProcessSnap);
return 1;
}
// 遍历所有进程
do
{
// 寻找 "wechat.exe" 进程
if (strcmp(pe32.szExeFile, "wechat.exe") == 0)
{
// 打开进程
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);
if (hProcess == NULL)
{
printf("OpenProcess failed. Error code: %d\n", GetLastError());
CloseHandle(hProcessSnap);
return 1;
}
// 遍历该进程的所有句柄
hMutant = NULL;
while (hMutant = FindNextHandle(hProcess, hMutant))
{
// 获取句柄的类型
dwPriorityClass = GetHandleInformation(hMutant, &dwPriorityClass);
if (dwPriorityClass == 0)
{
printf("GetHandleInformation failed. Error code: %d\n", GetLastError());
CloseHandle(hMutant);
CloseHandle(hProcessSnap);
return 1;
}
// 如果该句柄类型为 "mutant",则关闭该句
