I think what you want may be called an 'Event us'. You have a queue (Bus) of elements of type Event (Event is the type you define to contain the data). The thread is locked in the call to 'pop()' Anytime you want to send more data you just push a new element into the queue The thread gets unlocked and gets the new data Of course you may want to try another if more than one thread are allowed to handle the same event, but that won't be difficult if the first steps are understood. I invite you to take a look to this <https://github.com/ichramm/cppmisc/blob/master/concurrent_queue.hpp> for an implementation of a thread-safe queue Pseudo-code: void thread_handler() { while (true) { Event e = queue_.pop(); // do somehting with e } } void trigger() { Event e (data1, data2, data3) queue_.push(e); } On Fri, Sep 2, 2016 at 5:30 PM, Alexander Carôt <Alexander_Carot@gmx.net> wrote:

Hello all,

I have a thrad function like:

void sj::eventTrigger(){ boost::mutex::scoped_lock lock(eventTriggerMutex);

while (eventTriggerActive){ dFC->eventTriggerLock.wait(lock);

/// do something with pointer-variable

} }

This function is executed by a eventTriggerLock.notify_all() – call from other objects and when I need to pass certain variables into the thread I have been unsing a global pointer variable.

Now my question:

I wonder if there is a way to get rid of the pointer variable and directly pass variables into the thread such as:

eventTriggerLock.notify_all(data1)

void sj::eventTrigger(int data1){ boost::mutex::scoped_lock lock(eventTriggerMutex);

while (eventTriggerActive){ dFC->eventTriggerLock.wait(lock);

/// do something with data1

} }

Any hint welcome – thanks in advance

Alex
