Talk:cpp/thread/stop token

I tried using the search for "std::stop_token" and it returned no results; I only found this page by using google search. How to fix?

MediaWiki:Cpp-search-list-cpp should probably be updated. — Radix (talk) 15:41, 24 April 2020 (PDT)

[edit] Cancelation & Exceptions & once_flag

I saw early versions of this proposal included exceptions, which were removed with some reasonable rationale <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1677r0.pdf> however, the only way to cancel a `std::call_once(onceFlag, f);` is to throw an exception. Are there plans to address this? It seems like either `call_once` should support `stop_token` or `stop_token` or the standard should provide an exception type meaning that cancelation is happening.

[edit] class example

A jthread stop_token example using classes would be useful.

void f1() {}
void f2(std::stop_token stop_token) {}
class c
{
 static void g1() {}
 static void g2(std::stop_token stop_token) {}
 void h1() {}
 void h2(std::stop_token stop_token) {} // thiscall + stop_token
 void main()
 {
 std::jthread a1(&f1); // function
 std::jthread a2(&f2); // function with stop_token
 std::jthread b1(&s::g1); // static method
 std::jthread b2(&s::g2); // static method with stop_token
 std::jthread c1(&s::h1, this); // method
 // std::jthread c2(&s::h2, this);// <-- not allowed?
 }
};
