Re: [Cppcms-users] some graceful way to close the CppCMS app

[Lee E. <lee...@gm...>]

This opens up a much better option - performing my loop inside the C++ code
and no in the shell script running it.
And i can also return a shutdown reason using some static variable in order
to control that loop - somewhat ugly this usage of static but works, and
better then sending it over to the shell.

the main will be something like below
and the usage will be something like:

runflag = 2; // reconfig
srv.shutdown();
