程式碼如下
#include <windows.h> #include <RestartManager.h> #include <stdio.h> #pragma comment(lib,"Rstrtmgr.lib") int __cdecl wmain(int argc, WCHAR **argv) { DWORD dwSession; WCHAR szSessionKey[CCH_RM_SESSION_KEY+1] = { 0 }; DWORD dwError = RmStartSession(&dwSession, 0, szSessionKey); wprintf(L"RmStartSession returned %d\n", dwError); if (dwError == ERROR_SUCCESS) { PCWSTR pszFile = argv[1]; dwError = RmRegisterResources(dwSession, 1, &pszFile, 0, NULL, 0, NULL); wprintf(L"RmRegisterResources(%ls) returned %d\n", pszFile, dwError); if (dwError == ERROR_SUCCESS) { DWORD dwReason; UINT i; UINT nProcInfoNeeded; UINT nProcInfo = 10; RM_PROCESS_INFO rgpi[10]; dwError = RmGetList(dwSession, &nProcInfoNeeded, &nProcInfo, rgpi, &dwReason); wprintf(L"RmGetList returned %d\n", dwError); if (dwError == ERROR_SUCCESS) { wprintf(L"RmGetList returned %d infos (%d needed)\n", nProcInfo, nProcInfoNeeded); for (i = 0; i < nProcInfo; i++) { wprintf(L"%d.ApplicationType = %d\n", i, rgpi[i].ApplicationType); wprintf(L"%d.strAppName = %ls\n", i, rgpi[i].strAppName); wprintf(L"%d.Process.dwProcessId = %d\n", i, rgpi[i].Process.dwProcessId); HANDLE hProcess = OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION, FALSE, rgpi[i].Process.dwProcessId); if (hProcess) { FILETIME ftCreate, ftExit, ftKernel, ftUser; if (GetProcessTimes(hProcess, &ftCreate, &ftExit, &ftKernel, &ftUser) && CompareFileTime(&rgpi[i].Process.ProcessStartTime, &ftCreate) == 0) { WCHAR sz[MAX_PATH]; DWORD cch = MAX_PATH; if (QueryFullProcessImageNameW(hProcess, 0, sz, &cch) && cch <= MAX_PATH) { wprintf(L" = %ls\n", sz); } } CloseHandle(hProcess); } } } } RmEndSession(dwSession); } return 0; }
