QT_获取正在运行程序的进程id(判断程序是否正在运行)
bool checkProcessRunning(const QString &processName, QList<quint64> &listProcessId) { #ifdef Q_OS_WIN bool res = false; HANDLE hToolHelp32Snapshot; hToolHelp32Snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); PROCESSENTRY32 pe = { sizeof(PROCESSENTRY32) }; BOOL isSuccess = Process32First(hToolHelp32Snapshot, &pe); while (isSuccess) { size_t len = WideCharToMultiByte(CP_ACP, 0, pe.szExeFile, wcslen(pe.szExeFile), NULL, 0, NULL, NULL); char *des = (char *)malloc(sizeof(char) * (len + 1)); WideCharToMultiByte(CP_ACP, 0, pe.szExeFile, wcslen(pe.szExeFile), des, len, NULL, NULL); des[len] = '\0'; if (!strcmp(des, processName.toStdString().c_str())) { listProcessId.append(pe.th32ProcessID); res = true; break; } free(des); isSuccess = Process32Next(hToolHelp32Snapshot, &pe); } CloseHandle(hToolHelp32Snapshot); return res; #elif defined Q_OS_MAC bool res(false); QString strCommand = "ps -ef|grep " + processName + " |grep -v grep |awk '{print $2}'"; const char* strFind_ComName = convertQString2char(strCommand); FILE * pPipe = popen(strFind_ComName, "r"); if (pPipe) { std::string com; char name[512] = { 0 }; while (fgets(name, sizeof(name), pPipe) != NULL) { int nLen = strlen(name); if (nLen > 0 && name[nLen - 1] == '\n') //&& name[0] == '/') { name[nLen - 1] = '\0'; listProcessId.append(atoi(name)); res = true; break; } } pclose(pPipe); } return res; #endif }
