Maybe I need threads in my rig control program, so here is a simple test.
//======================
// SprigThreadTest.cpp
//======================
#include <iostream>
#include <thread>
void f()
{
std::cout << "void f()" << std::endl;
}
void g()
{
std::cout << "void g()" << std::endl;
}
int main(int argc, char **argv)
{
std::thread t1(f);
std::thread t2(g);
t1.join();
t2.join();
}
Let’s see what happens.
% ./SprigThreadTest void g()void f() % ./SprigThreadTest void f() void g() % ./SprigThreadTest void f() void g() % ./SprigThreadTest void f() void g() % ./SprigThreadTest void g()void f() % ./SprigThreadTest void f() void g() % ./SprigThreadTest void f() void g()
Looks reasonable? Of course, cout is not thread safe, so we may have interleaved characters.
void f()
{
for(int i=0;i<10;i++) {
std::cout << "abcdefghij" << std::endl;
}
}
void g()
{
for(int i=0;i<10;i++) {
std::cout << "0123456789" << std::endl;
}
}
% ./SprigThreadTest 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij % ./SprigThreadTest 0123456789abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij abcdefghij 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789
