Tiny library that allows passing member function and lambdas as C-Api callbacks
Hello, recently I've found some interesting behaviour about the overload which is using lambda that have a capture by value.
int main() {
std::vector<void(*)()> fs;
for (int i = 0; i < 10; ++i)
fs.push_back(cbc::obtain_connector([i]() { std::cout << i << ' '; }));
for (auto f : fs)
f();
}
For some reason this code results this output:
9 9 9 9 9 9 9 9 9 9
Which is something I was not expecting.
I wander if it's a bug in the lib, or a function pointer just isn't able to hold state of the lambda properly.
