This might look fishy.I've had several cases where my app could not get Push Notifications (PNs) because of the firewall on its own server.You can't have EOL opening up an http connection to an application potentially behind a firewall.Rewritten tests: #include iostream int main auto test std:cout std:setw(15) "Foo" ' ' true ' ' 123456 'n ; test std:cout session std:setfill std:left std:uppercase std:boolalpha std:hex std:showbase std:setw(15) "Foo" ' ' true ' ' 123456 'n test / stream restored here test std:cout std:endl;.P, nullptr / move p, while leaving coin pour sex rapide pres de oursel maison 60480 nullptr in other.Edit, parameters obj - object whose value to replace new_value - the value to assign to obj.My thoughts are a mess more than usual, so watch out for potential nitpicks.I believe there are some ways to improve current code.Also, it must be possible to move-assign objects of type U to objects of type T edit.Struct session_t ; static inline constexpr session_t session; inline is used to deal with linker.The code uses name guard in the tests.Create an object only by using stream session.(Try it, and you get errors.).Alternative solution, to achieve the syntax above, I've used some of the new features of C17.
I agree with everything what @JiveDadson said in the comment.People will need to be either too smart or cause undefined behavior.You apparently cannot add new subscriptions or remove old ones except within the disconnect handler.I wasn't sure if overload resolution and ADL won't intervene, so I decided to return ostream on operator.After doing some Wiresharking on this, I'm plan cul pithiviers not really convinced this is so because it seems like under the covers they're doing Long Polling, so each notification coming in will cause a new http call back up to Exchange.Get relevant translations in context with real-life examples for millions of words and expressions, using our natural language search engine applied on bilingual big data.Return value, the old value of obj edit, exceptions (none) edit, possible implementation template class T, class U T T exchange(T obj, U new_value t old_value std:move(obj obj std:forward U (new_value return old_value; edit.Even within a corporate network there are firewall issues.N return *this; ; edit Example Run this code #include iostream #include utility #include vector #include iterator class stream public: using flags_type int; public: flags_type flags const return flags /Replaces flags_ by newf, and returns the old value.
Naming, would it be better to use stream_state_guard?
And just for reference: sessions can be nested.
