Many ways to do it; simply put, the thread need to be able to put the data
into a buffer that the main thread can read from, in a thread safe manner.
My preferred way of doing this is using a producer-consumer pattern;
basically a queue with many producers and one consumer.
You may want to look at Boost.LockFree; especially the example
http://www.boost.org/doc/libs/1_57_0/doc/html/lockfree/examples.html
The global data buffer is nice too; make sure you use a thread safe buffer
( or data structure ).

(make sure you read #threadsafety
http://www.boost.org/doc/libs/1_53_0/libs/circular_buffer/doc/circular_buffe...
)
Good luck

Using boost, I start a thread from the main process as such.
MyWorkThread newThread; newThread = boost::thread(newThread);
And in the worker thread class (MyWorkThread), I have a read function which reads from a USB device as much data as it can deliver. This function can be called several hundred times a second.
MyThread::read() } //... while () { MyData data;
if (hasMore(dev, &data)) // lots of data here // need to get it back to the main thread } } }
I'm trying to figure out how to efficiently get this data back to the main process to be placed in a buffer since it can be called so often.
- Would making a callback to the main process be the way to go? If so, any pointers how using boost? - Or should I just have a global data buffer and store it directly?
