Manual cout reset only
As far as I know, streaming std::endl
in std::cout
will be hidden. I understand that this behavior makes sense for most applications.
My problem is that I have some output that uses multiple std::endl
and therefore clears the output. This is very bad for the performance of my program and also causes a lot of graphical glitches as I jump a lot.
So my question is, can I say std::cout
wait from next reset until I explicitly call std::cout.flush()
or thread std::flush
in std::cout
.
If possible, I would also like to know how I can then change it, because it doesn't always make sense to me.

Use std::cout << '\n'
instead std::endl
. This avoids a flush after each line. std::endl
will always be short-lived, since that is his goal. There is no way to disable this behavior. However, there is no need to use it std::endl
at all.
If you want to increase the buffer size for standard output, you can try increasing the buffer for cout .
