在我下面的测试代码中似乎是线程安全的。我可以Poco::Logger
在多线程程序中使用吗?
static Poco::Logger *pLogger;
class MyRunnable : public Poco::Runnable {
private:
std::string _name;
Poco::Random _rnd;
public:
void setName(std::string name) {
_name = name;
}
void run() {
for (int i=0; i<200; i++) {
pLogger->information("info from: " + _name);
_rnd.seed(_rnd.next(65532) * _name.size());
Poco::Thread::sleep(_rnd.next(13) + 1);
}
}
};
这是测试主要:
int
main ( int argc, char *argv[] )
{
Poco::Thread thr1, thr2, thr3;
MyRunnable *pMyR1 = new MyRunnable(),
*pMyR2 = new MyRunnable(),
*pMyR3 = new MyRunnable();
pMyR1->setName("r1");
pMyR2->setName("ra2");
pMyR3->setName("runable3");
Poco::FormattingChannel *pFCFile = new Poco::FormattingChannel(new Poco::PatternFormatter("%Y-%m-%d %H:%M:%S.%c %N[%P]:%s: %q:%t"));
pFCFile->setChannel(new Poco::FileChannel("test.log"));
pFCFile->open();
pLogger = &(Poco::Logger::create("FileLogger", pFCFile, Poco::Message::PRIO_INFORMATION));
thr1.start(*pMyR1);
thr2.start(*pMyR2);
thr3.start(*pMyR3);
std::cout << "starting..." << std::endl;
thr1.join();
thr2.join();
thr3.join();
std::cout << "end." << std::endl;
return EXIT_SUCCESS;
} /* ---------- end of function main ---------- */
