Hi Frederic,
I did not understand your comment...
My point was that I do a cond wait before I call async(read|write)
From within the callback function, I do a notify so that the next async command can be executed.
Will this not result in same functionality as you mentioned where wait is done after calling async(read|write) ?

Best Regards,
Nishant Sharma

wait right after otherwise, you will never call async_(read|write).

std::mutex and std::condition_variable are just fine.
