C++ (Cpp) SetLogDestination Examples

Example #1

File: backup_master.cpp Project: simon-rock/backup_d

int backup_master::init(const char *db_name, const char* ip, const char * user, const char* psw)
{
	// glog
	InitGoogleLogging("backup");
	SetLogDestination(INFO,"./log/info_");
	SetLogDestination(WARNING,"./log/error_");
	SetLogDestination(FATAL,"");

    // check user id
    if (getuid() != 0) {
        std::cout <<  "erro root privileges needed" << std::endl;
        LOG(WARNING) << "erro root privileges needed ";
		FlushLogFiles(INFO);
        return BK_ERROR;
	}
    
	// init pref
	if (m_pref.login_db(db_name, ip, user, psw) == BK_SUCESS &&
		m_pref.check() == BK_SUCESS)
	{
		POSTMESSAGENODATA(CONFIG_COMPLETE);
		return BK_SUCESS;
	}
