c++之std::thread多线程的使用和获取pid/tid

// thread example
#include <iostream>       // std::cout
#include <thread>         // std::thread

#ifdef _WIN32
#include <>
#define getpid _getpid
#else
#include <>
#endif

void foo()
{
	// do stuff...
	int pid = getpid();
	std::cout << "p,t,first thread foo\n";
	
	
}

void bar(int x)
{
	// do stuff...
	int pid = getpid();
	std::cout << "p,t,second thread bar\n";
}

//c++之std::thread多线程的使用和获取pid/tid
int main()
{
	std::thread first(foo);     // spawn new thread that calls foo()
	std::thread second(bar, 0);  // spawn new thread that calls bar(0)

	int pid = getpid();
	std::cout << "p,t,main, foo and bar now execute concurrently...\n";

	// synchronize threads:
	();                // pauses until first finishes
	();               // pauses until second finishes

	std::cout << "foo and bar completed.\n";
	system("pause");
	return 0;
